I'm just gonna address this before I go on with the rest of my post:

[EDIT] I would like to quote a certain black Scottish Cyclops. "If I were a bad Demoman, we wouldn't be sitting here discussing it now would we?". Replace Demoman with CoD and you can pretty much get my point.
What he means, is that if he was a bad Demoman, he wouldn't be alive, and would not be able to talk to the person interviewing him. Because he would be dead.
Now that that mess is cleaned up, I'll get to the rest of your point.
The reason anyone talks about anything, is because it matters to them to a certain degree.
That is why I talk about religion, Jersey Shore, Justin Bieber, Country Music, and many other things I really really hate.
All of these topics matter to me because I'd rather they not exist, and I talk about them to bring up examples of how much better the world would be without these things, and how people who like them, must have something wrong with them (joking, they're not
all bad).
So please do not get the impression that just because someone talks about something, that the thing they are talking about
cannot be the worst thing ever. I talk about Naruto, and I think it is an extremely terrible anime with the worst fans ever. That doesn't make
it good.
Back to CoD now. I will be buying MW3 because it looks like it will play like MW2, and have a revamped weapon/perk/map/combat system. The feel of the game looks like MW2, which I really enjoyed. Just like I am buying Skyrim because it looks like it has that Oblivion feel to it, but is getting revamped. I am not saying that it is Oblivion with a new skin, because they are changing a great many things with Skyrim as well as MW3. I just mean that I am buying it because it looks like a game I will enjoy.
I think that addresses all your concerns...
Oh, one more thing: you'll find there is a great deal of discussion value in topics that have a great deal of gray area. You won't get much discussion value out of a "The holocaust sucked" thread, but you'll get a brutal flame war if you say "Star Wars episode 3 is the best movie ever". Here on the internet, people are more likely to say "you are wrong" than say "you are right"
