This is one reason I think community notes style algorithms is where we'll probably see pretty much all community voting/moderation head over time. It's just objectively better since it basically fixes this 'glitch' in straightforward systems.
I think this got flagged initially because PG doesn't have anything to say about 'wokeness' that we have not heard many times before. He doesn't like it (big surprise) for exactly the reasons that you'd expect someone like him not to like it.
A moralistic ideology acting holier than thou is nothing new. In the 80s (and for sure time after) evangelicals had their "Moral Majority."
But nobody really cares until an ideology starts regularly driving harmful actions, at which point there starts to be a lot more push back.
For that matter Trump and MAGA have no degrees in psychology and sociology. Despite this, they were much more in tune with the American public than the Democrats with their fake intellectualism.

This is top to bottom a more thoughtful, nuanced take on essentially the same topic. The main difference is that saying stuff like "class of bureaucrats pursu[ing] a woke agenda" and "woke mind-virus" is fashionable among SV elites today, and it was not in 2004.
