Liberal values only work when they're universal.
If I'm allowed to live my life the way that I want, and you're allowed to live without your life the way that you want, and that's a compromise that's a lot easier to make.
The authoritarian bend has changed the calculus.
"use the pronouns or we're sending the police to arrest you" -- oh? well that's fine, but you don't get to ask just be left alone anymore.
"take our vaccines or you aren't allowed to have a life anymore" oh? well that's fine, but don't expect me to get worked up if you want to get an abortion and can't.
"We're going to use schools your kids are forced to go to by the state to indoctrinate your kids" oh? Well that's fine but I hope you don't think you've got a blank slate, you will be fought against.
Losing liberalism ends the moral framework the left had benefited from for generations, and the sooner they realize this the sooner they can come back to the light.
It becomes a new classism. Instead of liberalism for everyone, it's different levels of freedom for people of different spots on the political bingo card.
Hopefully after they're absolutely trounced in the next few elections around the world they are reminded that they aren't entitled to votes and they need messages that apply to more than just a few people.
