Marx Madness for theory, Chunka Luta for modern indigenous liberation, and 5-4 pod for shitting on the Supreme Court (though, because it’s within the framework of the current settler government, it can sound a bit on the liberal side, especially in the earlier seasons. It’s still enjoyable though because they do point out the hypocracy within the system even if you’re allegedly playing by the rules)

Edit 1: Also, Some More News/Even More News are pretty good if you like a little bit of comedy with your existential crisis.

Edit 2: The Minyan if you like to learn the intersectionality of Judaism and communism. Episode 15 is a 5 hour long analysis of the Exodus story and why the biblical/talmudic versions are completely fucking wrong.
