What brings out the worst in left 4 dead players?

Last night was a good example of the types of people that play left 4 dead.

The first game I joined, the other players started making fun of me because of my deep southern accent. To me - that shows a lack of respect towards other people, and an intolerance to other people. It also shows the maturity level of some of the players.

I personally do not see what the big deal is. Does it really matter if the person is white, black, tan, northerner, southerner, male, female,,,, - no, it should not matter.

We are all people, we all have feelings, friends, family and loved ones. We should also be able to play a game without being harassed.
