Individual heterosexual women came to the movement from relationships where men were cruel, unkind, violent, unfaithful. Many of these men were radical thinkers who participated in movements for social justice, speaking out on behalf of the workers, the poor, speaking out on behalf of racial justice. However when it came to the issue of gender they were as sexist as their conservative cohorts.
Before you were born, your parents weren't as boring as they are now. They got that way from paying your bills, cleaning your clothes and listening to you talk about how cool you thought you were. So before you save the rain forest from the parasites of your parent's generation, try delousing the closet in your own room.
In the past, when gays were very flamboyant as drag queens or as leather queens or whatever, that just amused people. And most of the people that come and watch the gay Halloween parade, where all those excesses are on display, those are straight families, and they think it's funny. But what people don't think is so funny is when two middle-aged lawyers who are married to each other move in next door to you and your wife and they have adopted a Korean girl and they want to send her to school with your children and they want to socialize with you and share a drink over the backyard fence. That creeps people out, especially Christians. So, I don't think gay marriage is a conservative issue. I think it's a radical issue.
