Yah, you're not going get a very good reaction by throwing terms like "ragheads" around. This is NOT a game about Americans killing Arabs, and it never will be.
Also I should be able to join all American teams.
Do you mean all American players or characters who are all American?
It would be nice to be able to set a preference for side, sometimes I get 3 or 4 games in a row playing one side and want some variety.
