This is essentially what I used to think as well, until I spent more time there. There's some stock phrases busted out, and some users probably leave it at that and don't engage beyond it.

Basically as part of their extremely liberal ideology, they analyze things through a materialist lens, even the non-marxist liberals there, and through that there is a lot of seeking out of what material causes and contradictions have lead to where we are which can be really neat.
