I spotted this buried deeply in an otherwise-boring discussion on tvtropes.org, and it has much wider application and deserves much wider distribution. I made a mental note to re-post the quote on my site, then couldn't remember exactly which page it was on, and spent many hours searching, over the course of a week. Now, I finally found it again.
Let me paraphrase the OP's point: "I have this opinion. I don't understand why people have differing opinions. But instead of genuinely asking why other people hold those opinions, I'm just going to say: you have those opinions because you are defective. Tell me why you are defective." Way to go, Ace.
