That’s not the right comparison. He didn’t commit suicide because he was ashamed of supporting gay rights, he was ashamed of wanting to cross dress and of having engaged in the activity. Regardless of politics, that’s a pretty uncommon behavior. Most people don’t want other people to know they’re a sexual deviant of some kind. I’d guess that this behavior is much more maligned in conservative circles than liberal or left, for sure, but the point is that it’s not just the breaking from the standard beliefs of that side.
