Yes. I would definitely support laws prohibiting gays from doing each other at the restaurant where I'm trying to eat. I also support laws prohibiting them from doing each other in public restrooms, elevators, libraries, etc etc etc. I know, I know... horribly fascist of me.
But in the interest of fairplay I'll support laws banning heterosexual acts on the tables of my favorite restaurants as well. Especially since the participants will no doubt want a cigarette afterward! Happy now?
