This episode of the podcast then goes into a predictably confused discussion about the regimes that resulted from 19th and early 20th revolutions.
Particularly the Leninist/Stalinist and Maoist regimes that are commonly called "Communist". Despite the fact that a careful reading of their history shows that the communist revolutions in Russia and China were defeated by authoritarian nationalists. Just like the libertarian socialist revolution in Spain, and the democratic socialist one in Chile.
