It's just your tabloid fear-mongering at work. They said similar stuff about MW2 being a so-called terrorist simulator. It's just an over-reaction to get attention; like the guy who said that the world was going to end on May 21st.
yay! Now we don't have to listen to you snaggle-toothed British mucks in the multiplayer lobby.
In my experience I find the an accent better then hearing "I can not be killed, the player is cheating" comments, hearing "jackesses" who should be quiet and not talk at all, music from a player using mic and heavy breathing which indicates the player should
be seeing a doctor. I equate all of this to North America (which includes Canada) where our pride, ego, lack of common sense and stupidity knows no bounds for some. While I know the mute button is your friend you should not be forced to use it at all unless
there is a good justification to use it.
