With regard to backlash to trans, I think it is much more. Trans have become the guidon bearer for the political left and the backlash is happening toward the entire "left". Increasing numbers of liberals are disgusted with what the progressives have done to tarnish the good name of liberalism and are drifting right.
I see that the chatter from liberals who don't want to admit to themselves what the left has become and try to make it all about trans, but I think it is more than that. They instinctively want to view the world thru a "conservative bad" filter and when in agreement with them put weasel words to say, "the asshole I'm agreeing with on this almost sounds sane" because it is more palatable than "my tribe has gone nuts."
