Just saw your post in the MW2 community thread, and trying to avoid a flame war I thought it was easier to post here.
I'm British and I think it's very unfair to judge all Brits on what some do, because in my opinion 80% of Americans do exactly the same on live. I refuse to speak if the game is populated with americans as all I get it "Oh my god, he's british. He's a fag. He's got a funny accent. Harry Potter?" People on live just have a very immature view on other countries/nations, it won't ever change as the Immature portion of Brits will argue with the Immature portion of American's, or vice versa, resulting in nothing but prejudice.
