A lot of the biggest critics of it are people who until they stood up to this stuff in the last few years, were considered liberals.

Bret Weinstein warned everybody several years ago. Everyone responded by attacking the messenger. He called it though.

Shit, I come off as rightoid to many but I'm a registered Dem and used to post in the midwit politics sub constantly. I still have some socialist viewpoints. I started to recognize exactly what you mention: the inevitable backlash that would come if left wingers embraced this illiberal crap. Noticed that I'd get downvoted for daring to suggest crazy shit like "anyone can be racist". 

The Overton window fell off the track somewhere along the line...

This idea goes all the way back to Carl Polanyi's double movement theory, that any extreme collectivist action will inevitably swing in an equal or greater opposite direction as a response to interests. Everyone likes to pretend like this is something new, but it wasn't like everyone was a hippy in the 60's either. Someone had to have jobs.
