Because apparently for dudes who've got a compulsive need to be the smartest person in the room, "someone who's wrong in a really stupid way who has unshakable confidence that they're smarter than you" is their kryptonite. You can play dumb on almost any subject and their ego, their staunch belief that the masses are so far below them, will blind them to the fact that you're just fucking with them, and as long as you don't admit you're fucking with them or acknowledge that there's anything Off about what you're saying, they won't be able to stop themselves trying to get you to Respect Their Authority, and they won't be able to see that will literally never happen.
