What are your left wing manga/anime recommendations? I only got Ninpu Kamui Gaiden, because it is communist and ninjaic? You may shrug you shoulders, but a communist created all the ninja cliches, like a dude named Sasuke and the "Izuna Drop"! Unfortunately, the manga is from 1969, when the United States still had not erased all left-wing presence in Japan.
The Rose of Versailles, and Kaiji. Especially Kaiji, it's probably the most radical anime I've seen. But also The Rose of Versailles is very very good too, especially the last 10 episodes.
