Dudebro at bus stop: I don't get that guy from REM. He's gay, right, but why? He's famous, he could get laid with tons of girls, and it's so much easier to be straight. People don't pick on you so much if you sleep with girls.
Me: Um... *bracing for argument* It's not a choice.
Dudebro: It's not? Oh. Huh. That makes more sense.
