the most annoying thing about people insulting in a game, is the fact that half of the server is actually "chatting" while standing still and distracted instead playing the game... so you try to charge the enemy when you realize that people behind you is arguing about racism instead forming a defensive/offensive line, ranged not shooting, knights standing still getting shooted down... so on.
luckily this almost never happens on EU servers... while in NA people tend to setup a boring talkshow about: Democracy, World War II, Racism, Capitalism...
there is facebook or any other random social network for that cmon...
