Why doesn't Yahoo Answers have a self-righteous bigot filter?

I see the most innocuous questions put by people who just want a sensible answer or point of view. Then you see the answers posted by total self-righteous, up-their-own-**** hypocrites calling them sad, muppets, shallow, perverts - I was even called a silly boy the other day. Are these people really serious, or are they having a joke?
