Where's the left wing pipeline start these days?

My friend went from doing nothing politically to trying to go to a different useless lib protest every week. Which, hey, that's not nothing, great. But I'd like to get her thinking about why none of this does anything and what actually needs to be done, before that burns her out and she goes back to brunch.

Philosophy Tube posts once in a blue moon, Chapo has lost all its cultural relevance, and y'all can't shut up about Stalin. What do I casually recommend to someone these days?
