I'm an anarchist, I don't think Sankara was a "tankie". Maybe that's because I literally live in Africa and I'm out of sync with the "western left". He was, as you said, a ML that was heavily inspired by the Cuban Revolution and other Marxist/Maoist projects. And he upheld those values himself, he owned almost no material possessions and did practically nothing wrong, and admitted to any mistakes he made (such as the show trails going overboard). Like if western leftists (liberals) can't even critically support someone like him thats not my problem
