Moderators are not there to verify or factcheck every statement in a post. It is for those in the discussion to do that themselves, arguing why that is the case. The moderators are only there to provide an area for civil discourse. It is not the place of the moderator to simply shutdown someones post because they agree/disagree with it, that makes a bad moderator.

As such, insulting other patrons willynilly and accusing their parents of doing a really bad job would receives moderator attention on yourself due to lack of civility. Imagine you are at a restaurant with a few work colleagues, and in a discussion, you get up, shouting and insulting them. The restaurant manager would come along and ask you to leave, because you are disrupting the place.

This is what I believe Axalon is talking about, Moderators don't enforce right or wrong, they enforce civility and good conduct.
