Actually...I've noticed it tends to be mixed bag of what could be considered negative traits when it comes to America:
Crassness, crudity, overbearing patriotism and jingoism, outright arrogance and general insensitivity toward others without seeing any reason to be apologetic for these things. This article here by a Graphic Designer named Andy Rutledge is these traits condensed:

It was, I found a nauseating read. And not because I don't agree with many of the points he makes, but mainly because of tone. That, America is the be all and end all of the world wide stage and how everyone else is supposed to look up to her as a parent would a child.
It's just...so damn condescending. And while the above traits aren't necessarily exclusive to Americans, it's still how many are seen, and even present themselves on occasion.
As for the article, it's really non-news, I doubt there are any here who pay much attention to it anyway. xD
Hmm, well unlike you I agree with 99.9% of what that article says, albiet he seems to skip over thinks like America's pre-WW II isolationist policy. Some of his current political criticism is right on as well, I've been warning people about the Democratic party and it's censorship kick for a long time. Trying to convince people to give up their free speech rights in order to protect people from hate speech, and children from violent video games, and similar things. The big thing is that in the US the people pretty much have to give the goverment power, it's nearly impossible to get back though. The current administration is especially good at making arguements as to why we need the goverment to effectively protect us from our own freedoms.
As far as the general attitude of "exceptionalism" goes, I think it's right on. Like it or not, the world has undergone profound changes since the rise of the US. As much as people complain about us, the simple fact is that our culture is contagious, and even in fairly oppressive countries people have more rights than they did beforehand, our global policing also makes a huge differance for all the whining. It's like being a cop, nobody wants you around, and enforcing the law on them, until they need help.
Things like the "national firewall" programs you see are pretty much intended to try and prevent people from wanting to become even more American, and desiring more freedom from their goverments.
Generally speaking I think that the perception of American arrogance isn't as common as people think. Generally speaking there are two basic groups that see things that way, one are of course Americans who are being critical of their own goverment. The bottom line being that nobody wants to fight wars, pay higher taxes, or anything else, and argueing that we should stay out of certain issues is largely motivated by people really not wanting to have to actually DO anything, even if it's pay more money. Human rights, and maybe a world unity under constitution-like principles are fine on paper, but the bottom line is nobody wants to send their kids off to get shot over it. The bit about "Doing something" has always been the stumbling block for any nation, and the very freedom we represent also increasingly makes it harder for us to do anything.... the other group involved are simply foreign nationalists who think that their nation is awesome and should be running the world. To such people America and it's relative successes, and the way our very existance has changed the world, are an anethema. They might want to see similar things happen, but they want everyone to come over to THEIR way of doing things rather than them going over to someone else's
To an extent there is no real way to do some of the things that America does without being called "Arrogant" but on a lot of levels that can't be argued because we're right. Still, when our nation has only existed a little over 200 years, and you tell a nation with 5000 years of history they're doing it wrong... well, that causes issues even when your right. Hundreds and thousands of years of cultural identity builds up.
In general though, I think the parent/child relationship is pretty accurate. But then again understand I believe for humanity itself to survive we're going to need to unify the planet. I don't think we can seriously conquer space until that happens. I happen to think American principles are the only ones that could truely unify everyone under any reasonable degree of freedom.
Still, the thing is that while that attitude is arrogant, that doesn't make it wrong. What's more, in general the US tends to behave rather humbly in it's actual dealings with other nations unless there is a direct conflict. I don't think many people can really say Americans are arrogant, unless it's Americans argueing politics with other Americans. I think the actual complaint is that the actual idea of America is arrogant, as is the way we spread our ideas of freedom around.... basically "how dare you prove something like that can work". I think the fact that Americans tend to actually be pretty tolerant and accepting when we travel abroad (the "obnoxious tourist" is a universal stereotype, and not specifically true to any group), and that's kind of insufferable when all is said and done.
I do admit that guy in the article states things "arrogantly" but then again I don't think one can make a point about national principle like that without doing so.
