I forget who I was listening to or reading that said something like "political doomerism is the last stage of your liberalism before it dies"

Essentially, the point was that as people become radicalized they will learn all of the problems of capitalism and gain class consciousness and then conclude that any action is pointless.

They'll essentially sit at home, talk about activism, but judge both people working within the system as well as people protesting or demanding change from the system. It's a way in which a radicalized class conscious person is held in a state of inaction. Essentially making them useless.

It was a good little one sentence summary of those people. I'll try to remember who said it.
