I’ve wondered about this a lot, as well. I think partly it’s because straight men hold more power than anyone else, anywhere in the world, and going after them can badly backfire against their movement. So they attack LGB people who have much less power, in comparison. Then again, so many transwomen are straight men who go after lesbians (for the “validation” by the looks of it), and the rest are gay men, so they attack LGB people for rejecting their advances. I think it all stems from a volatile mix of acute frustration and intense narcissism in the trans people who do go on attack mode. Not all do, from what I’ve seen, but the few sane, reasonable trans people I’ve interacted with online told me they get doxxed, harassed and threatened like everyone else. They don’t want anything to do with the Transcult but they’re scared to say anything too.
