The French revolution. It's the French revolution. [On English YT, I'm actually curious what French YT is like with it]
I mean seriously, go look up the French revolution on youtube right now. For an event that is not only important for Marxists to understand and represents an important case study of class struggle through the ages, but also has some dissenting opinions in the historical and histiographic academic sphere, basically all of the videos (save for maybe one or two documentaries) are from, at the best, an extremely Girondist perspective, if not an outright Ancien one.
I mean you can get good stuff on the Russian and Chinese revolutions by people like Finbol and Onedime*, and there's plenty of stuff on modern china and imperialism and all that [not saying that this content shouldn't be produced, just that I don't think i could add much to it].
But on English YT, you can call Robsepierre the most evil person in French history and no one bats an eye. So if I ever have the time, setup, and self loathing it'd require to make something on it, I would definitely like to.
(*I am aware that 1dime might have said something apparently Patsoc like on a podcast or something a while ago. I can't find it again [thanks to reddit nuking thedeprogram] but if that's a problem I just want to say I'm aware of it.)
Edit:People in the comments have pointed out that 1dime is not a communist, is a moralist, and a patsoc. I still reccomend his videos on the cultural revolution as decent sources not plagued by the usual garbage, but [as with anything, bit especially here] view it with a critical lense
