Refuse to 'accept' it as normal or natural. Refuse to kowtow to those who demand we do so. Call it what it is. Take a stand. I'm not talking about hating people. We all probably know and like or even love gay people. That's one thing. Patting them on the back and congratulating them, telling them they have so much to be proud about is another thing. You can love someone who is all kinds of F'd up. And you can either pretend they aren't, or you can, within your limitations, attempt to help them get un F'd up. Same with gay people. You can love your friends who are gay, but you don't have to pretend that it's normal or okay. And as for what you can do in the broader sense, you can take a stand against and vote against things like gay parenting.
