Apologies Robert, but I have to disagree with you in the strongest possible terms, though I imagine you'll do the same with me. The problem is that your trying to deal with the culture as individuals, figuring that "well I had muslim roomies, so I know what they are like" when those people were themselves the outsiders surrounded by a foreign culture that you talk about when dealing with soldiers. What's more a people cannot be judged by individuals within it, but by the people as a whole. A person (single) is fine, but a people, when they all get together and are taken as a whole, is something entirely different. This is the root of sociology, which is really the only way of dealing with or understanding things on a national or cultural level. Liberals, the peace at any price movement, and humanitarians like to try and focus on individuals and put a human face on problems, but that is ultimately counter productive in the large sense because what a person is like when approached in relative isolation as an individual, and what they are like when immersed with others of their own kind is entirely different. As much as people hate sociology in these arguments, it's the real deal and is exploited constantly by advertisers and similar sorts every day, and to great effect.
The point of these links, which is just a tiny sampling is to show Muslim culture and how children are conditioned from an early age. Hate anyone non-muslim, kill them, Jews and Americans being particular targets. The entire Western World being likened to the devil. This is to say nothing of videos you can find of thousands upon thousands of Muslims running into the streets to pray while their leaders talk about murdering Americans and the people cheer and chant approval.
The thing to understand is that while actual fighters are a minority, the culture itself supports this behavior, and producers more fighters, keeping the ideas and rhetoric alive. Like people anywhere they are cunning enough to use what opportunities they are given, so they play to the media, liberal sentiment, and similar things. After all it doesn't take a rocket scientist to figure out that it's easier to beat the US military by going to the media and appealing to the naïve American left, than it is to actually fight us. If we give an opening due to morality it's going to be exploited. What's more on an individual level these guys are smart enough to conceal themselves when in a foreign culture, they are going to play the game, maybe even getting married and having children unaware of their true colors while waiting for the right opportunity. We've had cases with seemingly upright professors with a liberal seeming idealogy actually running information hubs for terrorist networks out of universities in the past. Not to mention the Muslim quasi-infiltration of the Latino/Hispanic population. The quickest way for a Muslim to get into the US undetected is to get into Mexico (relatively easy) and then sneak across the border that way, and then hide within the illegal fringe communities. Real Latinos might realize something is up (but they can play kindred spirit) but to an outsider if they primarily speak Spanish or pretend to, they can easily pass as being Latino and justify why they don't have any paperwork and exist off the radar. Believe it or not this is one of the major "under the table" reasons for concerns over border security as evidence of this going on was detected shortly after 9/11 and that's where a lot of concern over Muslim sleeper agents came from. This is one of the avenues of approach terrorist organizations teach their operatives.
Now, where you are correct is that within "The Muslim World" there are a lot of ethnic, religious, and cultural sub-divides. The thing is though that hatred of, and a desire to destroy Jews and The Western World is a unifying influence which factions that normally hate and prey on each other can agree on. This is why during Desert Storm, Saddam was able to hide military assets over the Iranian border to protect them despite the history of antagonism with Iran. It's also why you hear constant cries for "Jihad" as the idea is for ALL Muslims to put aside tribal and cultural differences to rally for a single purpose, and why Bin Ladin and Saddam both tried to style themselves as modern versions of Saladin, and invoke images of Crusaders. Yes there ARE minorities of people down there who are not Muslim, but they are not the controlling force, so it's very much "The Muslim World" as that is the overwhelming controlling force of the region.
The problem as I see it, is that the US is not morally equipped to fight a war against a culture, as it's contrary to everything we've been taught about how things should work. We can fight nations and infrastructures, but the idea of a culture like this where the "bad guys" are not a radical fringe, but rather the progressives are, is pretty much alien to everything we're taught to believe. This is why you don't see many videos like the ones I posted in the mainstream because people generally tend to find it too disturbing to see how things work, and exactly how deep this rabbit hole goes. The Muslim version of "Seseme Street" pretty much tells them to kill Americans and Jews and conditions the populance from a very early age to be a specific way. A very small minority might actually go and train, infiltrate the US, and prepare to set off bombs or whatever, but the culture itself supports them, much like we tend to support our military. Of course when questioned by foreigners with a gun to their head (we have enough military in the region to pretty much wipe the place out right now) the average non-fighter is going to play to the media, especially seeing as his words can paralyze the military more than all of the fighters working in concert could do. It's sort of like how if a foreign invader occupied the US, and some soldiers came up with machine guns and cameras and asked if you supported them, you'd say "yes, yes I do" and make it sound good because your no soldier. At the same time when your together with other Americans and they aren't around you'd be supporting what you see as the resistance.
As I said, I don't expect you or others to agree with me, but while I usually don't do so I put up a few links. You can find more if your REALLY curious you could fill up pages with that stuff.... people wonder sometimes why I think what I do... well there you go. On top of that I also had "anti-terrorist training" when I worked for the casinos, and should even have a certificate from Homeland Security around somewhere. At the end of the day I simply think that on this subject messages of tolerance are naïve, and miss the point that while we're teaching tolerance, those cultures are bombarding their kids with messages of hatred and intolerance from pretty much the beginning of their ability to think. If you consider how much your childhood heroes in cartoons and such influenced you, as did what you learned in school and so on, imagine what it's like down there when they have an analogy to Mickey Mouse beaten to death by a Jew. Think about how that kind of thing doubtlessly affected an entire generation of Muslims, and then consider that it's constantly reinforced.
In closing though I'm going to say something a little contrary to the rest of my post. Islam itself is not the problem, the cultures built around it are the problem. People who bring up all the violence and intolerance in the Qua'ran miss the point that most religions are the same exact way, with rare exceptions. The first thing a religion does is present itself as the absolute truth and a path to salvation, and then pretty much mandates that everyone follows it or should be made to follow it. The Bible is full of tons of stuff both encouraging peace and tolerance, but then telling you "thou shalt not suffer a witch to live" and similar things, with the broad definition being that anyone who follows another religion is a witch because there is only ONE true religion and all others are the teachings of the devil in disguise. Christians shed tons of blood, as have Hindus, and even Buddhists, Taoists, and others have effectively been in their own little wars, even if mostly defensive ones.
I believe Islam can be practiced peacefully and alongside other religions, cultures, and societies. If you look at how Christianity adapted to the point where unless someone tells you your unlikely to even know what religion they follow, it's easy to see how Islam could adapt the same way without the sacred mosques, violent laws about drawing pictures of mohammad, need to kneel and face the holy land, special prayer rooms, etc. The problem is less the religion than the cultures that have been built up around it, which is a big part of why I believe if we effectively break the cultures in The Middle East, Islam will then be able to reform and assimilate better into global society. Islam is simply at a point where it pretty much demands everything be on it's terms, rather than on the terms of the rest of progressive global society. You can see the problems and how deep the rabbit hole goes when religion is used as an excuse to oppress 50% of the population (women) and outside women when meeting with officials are expected to adopt a submissive demeanor towards men no matter what kind of rank or authority she might otherwise have. When you look at that on a cultural level, and the degree of intolerance for people who disagree, you begin to see the problem. Can Islam be practiced while ignoring those bits? Of course it can. People practice christinity without running around killing anyone that's believed to be a "witch", although at one time that did happen.
I write this to end with a message of hope, and to show where I'm coming from in an overall sense.... and no, I do not believe most people from those cultures want progress. If that was the case when we liberated nations like Iraq and Afghanistan they wouldn't have immediately defined themselves as Islamic states, and we would have achieved originally stated goals like the liberation of women. Some people practicing Islam who were born abroad and entirely separated from those cultures DO managed to assimilate into society, showing that it is possible. Of course there is also the side issue of Muslim offshoots born away from The Middle East, like the "Black Muslim" faith which calls for race war as much as religious war, revolving about a guy called Yakub (look him up, Wikipedia has a fairly accurate version) who created white men to oppress black men in a tyranny which is soon destinied to fall apart. This doctrine is largely what inspired Manson's "Helter Skelter" the race war which whites would lose, but through preparation and the leadership of guys like him would one day recover.... but as I said that's just another face of the problem, and has nothing to do with the central issue this focuses on.
