I don't see white women standing out in their behaviour, but they sure will always remain an acceptable group to beat up on without losing your progressive or otherwise credentials.

Karen at this point is always pejorative and pretty much just not well hidden sexism at best.

That's been the most impactful change of the entire progressive movement. It's now ok to be sexist and racist against white women. It's feminism stood on its head. The reduction of white women to a meme has been incredible to watch. No idea why anyone would be for this.
