Basically when PG was writing about stuff they considered part of their in-group then it was great and wonderful.
When he writes about stuff that's no longer aligns with their existing political in-group's beliefs (his arguments against the wealth tax [0], his essay about conformism [1], his essay about economic inequality [2]) - suddenly he's 'disconnected' and they're 'disappointed' in the essays.
I thought those essays were great and the points were interesting/well argued. I liked his old essays too.
I find the tribal responses to them (and the comments here) to be lame.
