It's this. Attacking gay people is no longer acceptable to enough people that conservatives can get away with it as a culture war tact. They've moved onto trans people which is more successful because there's a lot fewer trans people. We're seeing a LOT of bullshit getting flipped around and making people mad about things they didn't use to care about. The drag-hate is a good example. Tons of examples from history where drag is supported and now it's a major battleground? Bullshit. Just another way to find a convenient target for the right to hate.
