Please excuse me for intruding, but I thought these would make nice additions. In a pointing-out-the-blindingly-obvious kind of way.

The Galileo Fallacy: The fact that everyone disagrees with you does not make you Galileo; just because an idea is unpopular doesn't make it right.

The Gadfly Corollary: The fact that other people are pissed off about what you've just said does not make your statement automatically correct; you may just be an asshole.

Both are paraphrases and originated in this blog post.
