I will have to add to this a real problem that wikipedia is having.

Feminists! Feminists have offered bounties for adding feminist literature into citations. And, they are there. Like the 77 cents for every dollar that won't go away no matter how many times its disproven.

Feminists are a large group, with a large supporting. So, if there was ever any kind of democratic voting, they are likely to win. Facts do not seem to matter to this demographic. Perception is far more important.

What will happen as things get more fired up is that the feminists would soon control wikipedia. (its happened elsewhere) And then, the group that wants an honest, factual encyclopaedia will have to start again, somewhere else.

So, there has to be a something from the get go that allows for the banning of destabilizing forces. One way this could come into play is that a poster gets enough votes that they are a troll, then their comments get put into the troll category. Trolls see it, and non trolls don't.
