Yeah, it’s the argumentum ad argumentum! You too can be Socrates, attack your opponent’s logic. Start with the generalization and don’t stop (argumentum ad nauseam) until he admits we can never know anything. Then after you’ve rendered him into a Harry Krishnut, attack his punctuation and spelling (argumentum ad apostrophe’um).
Go git em! (Argumentum ad sic ‘um.)
Wouldn't it be simpler to push him down a flight of stairs or to hit him with a piece of lumber?
