I just don't agree on the Frankfurt School
I am well trained in the dark arts of far left academia, and Adorno/Horkheimer were barely ever mentioned. Marcuse was faddish in the 60s and maybe has some catchment in the sexual revolution but not much further. Benjamin was only popular with literary types. Again, I truly think Habermas was the most important figure due to his embrace by liberals with actual power. I don't understand the fascination with the Frankfurt School when clearly the more significant figures in post-Marxist leftism are French - Fanon, Sartre, Foucault, de Beauvoir, and Deleuze are vastly, crushingly more influential on the contemporary left than the Frankfurts. I know a lot of right-wing types like to draw a straight line between all these figures, but I strongly reject that - these dialogues happened without significant reference to Adorno/Horkheimer/Marcuse. I know there's anecdotal evidence like the Marcuse-Davis connection, but I've never seen any strong textual evidence that leftist thought as a whole would be any different without the Frankfurt School.

My friend, I would like to introduce you to a pair of characters called the Koch brothers.
"Once again the "dismantle systems of oppression to achieve liberation" rhetoric comes from them and one hears it all the time today"
Oh come on, this is fundamental to every liberation movement - communist, nationalist, whatever - that's ever existed.
"That's even in the Wiki entry!"
This is less of a compelling argument than you think, but I'll look into the citation. I don't consider every criticism of the Enlightenment or Western rationality to be a barbaric descent into esotericism, but I'll look at this with an open mind.
