Unlike the situation you're failing to attempt to compare to, nobody involved in this false equivalency setup made any attempt to back out of the debate, so please stop being obtuse.
EDIT: To make this absolutely clear - I don't think the opinion that guy stated was worth defending. What I take umbrage with is the "oh no, you don't get to back out of that" attitude that was taken in response. In essence, what you're doing right now is backing someone who is teaching folks to never concede a damn thing by continuing hostility and abuse even after the other guy backs down. That's what I objected to. I'm not sure about you, but I like the idea of a forum where folks are allowed to learn from their mistakes.
