Why is there so much disrespect on yahoo answers (mainly regarding political affiliation)?

I have noticed that many of the questions on the politics section are ones such as "Why do liberals hate democracy?" and "Why are all liberals so uptight and rigid?" and other insulting, untrue accusations. I am a liberal myself, and, to be fair, I have noticed that some of the insults have been going the other way, but I still believe they mainly come from the right. Either way, it is totally unverified and uncalled for, so why do people do it? Opinions?
