I find them mildly sexist but we can agree to disagree.

With right-wingers you really need to separate them into two camps. There's the actual bigots and then there's the people who are simply well-intentioned but old fashioned. The ones who legit just hate women and gays are a write off but the rest of them can be easily swayed. I've spent time in isolated work camps with people like this and you can build bridges with them. They might not outwardly state they've changed their minds but you just learn to accept that "/u/insta is one of the good gays, not like the rest of them" is a starting road to acceptance. And honestly most people really don't care that deeply about these issues once pressed, lots of right-wingers are painfully libertarian (even to their defect) .

At this point the right-wing culturally how so little power if some random 70-year old thinks that civil unions are okay but marriage is only for straights, people have to understand that this opinion is basically harmless at this point.
