Where is this documented?

Seems incredibly biased to say that right-wing moderators are dangerous to society. Just because someone has a more conservative outlook, doesn't mean they are a menace. A little bit shocking that needs to be pointed out.

If you're a left-wing moderator or a right-wing moderator, there is no way I should know that unless you tell me. Any moderator that is actively and purposely applying their political philosophy to a forum that reaches thousands of people is dangerous to society.

I didn't read OP as saying that right-wing moderators are per se are "dangerous to society", but that it being just one viewpoint represented (especially if, as "a right-wing contingent" implies", it's a single group of people) could be,].
