Ad hominem? I don't know if you know this, though you probably don't, but 'ad hominem' is a category of logical fallacy, committed when one argues that one's opponent's argument is wrong because he is, por ejemplo, an asshole or a pedophile or a loser or a dildo. At no point have I argued that your position is logically incorrect because you are an asshole. I've only ever argued that you are incorrect because your logic is dumb.
Move along.
