I liked it too. I didn‘t know anything about about Chinese history. I found that part fascinating. Some parts of the history of the black Panthers I was not familiar with either.
His point about paranoia and fear keeping people from any meaningful action was very well made!
Finally he affirms the belief in reason as the only way out. Even though I mostly agree, it felt a bit disappointing and uninspired as an ending. I mean Jeez, The enlightenment happened in continental philosophy centuries ago, but that did not really prevent any of those atrocities he himself described in the series. Imperialism was in part justified by the philosophies of reason.
I also felt it was a bit too much about ideas and not enough about the material relations that produced them.
I don‘t want to be too critical. It was very thought provoking and well done!
