It's more about being politically correct to the point of absurdity.
In the real world, you go to a party and people make racist jokes, or sexists jokes. They use the terms midget and someone might *gasp* ask if someone is distinguished mentally-challenged if they're being an idiot. Are all these people horrible people that are racists, sexists, and hate the mentally challenged? No, they're people that can tell the difference between poking fun at something and being serious. GAF and forums in general are a collection of people joking around chatting with each other.
Treating GAF like a high security lockdown middle school inhabited by 10 year olds is a bit much.
