I think people on the left want to feel like they are fighting for something, but they will only fight for issues once they are basically solved because they are mostly cowards. Race & homosexuality aren't actually serious issues anymore which means the most cowardly can feel safe acting like they are fighting some grand evil that they have simply imagined. And in so doing their irrationality & their effort to find or create some pushback to confirm the belief that there is actually a struggle, causes them to behave in ways that are horrible & ultimately foster a deeply unhealthy culture, which then becomes associated with all the things they claim to defend, granting legitimate reasons to oppose anyone associated with any of it. I think the "progressive" left is more destructive to gay people than any group of bigots could ever hope to be.
