Normal gay people have always been surrounded by the fringe. The smart ones realized that and knew that generally not attracting public attention was a good idea.

I'm down with the gay rights movement so long as it's for ensuring that gay people don't need to deal with intrusions into their private life resulting in them losing their livelihoods and their ability to choose who they want to live with without government interference. But I think the problem is with the larger idea of celebrating "pride" is it's going to empower the increasingly fringe elements to also be very open and prideful about their sexual identities that go far beyond simply having a consenting partner and doing your business in private.

It's the same reason why the anti-gay stereotypes exist. Why do you think there was a stereotype that all gay men were pedophiles? Well it's because only the pedophiles were getting caught, the normal ones kept it private. But just because most gay men aren't pedophiles doesn't magically get rid of the ones that are. And if you ignore them they'll stick around and sink the larger movement.

As in this case, gay people don't properly gatekeep out the animal fuckers from their umbrella group, now you're associated with them. And if you want to continue to enjoy such niceties as married tax breaks and legal protections against being fired for being gay you have to go and explicitly shut down the people who are like "being gay means I rape animals" before that once again goes back into the culture war and becomes the stereotype, and some politician capitalizes on it.
