I think mostly human behavior.People who struggle to get their message across in real life,need to come to a net community and push their beliefs on other people.They are in the minoirty.They have no audience outside of the internet because they can put it all out there(thread/reply),without people laughing hysterically in their face after one sentence/comment.They are sick to some extent.They can't possibly live a normal life thinking the whole world will end soon,or daily they live in a country that is evil.They can't even live a life.They live through a thought,a theory,something nobody else believes exists.Truly sad.I feel for them.
