over half the posts are abusive

Yes unfortunately there are a lot of people struggling in this market, and they seek to ease their pain by aggrivating others.

Somehow they get it into their heads that their own life wont seem so bad if they make other people feel bad, then they can think: "at least im not as unlucky as this loser".
Truth of the matter is they are cowards, just like the bullies at school.

Pity them.
