I hate that phrase so much. It's not even so much as the flamboyant and obnoxious gay stereotype that gets flung around by people who use that phrase, but just when they see a same sex couple kissing, hugging, holding hands or showing any kind of affection around them. No, I think you do hate gay people if their behavior is enough to make you uncomfortable and in most cases, angry. Just be honest and tell them that they want them to go back into the closet than to pretend you actually care. People who use that line probably wouldn't use it on straight couples, so there's that. Why crap on people who've been crapped on for so long already?
