No offense to this site, I like it a lot so far, but I wouldn’t favorably compare it in terms of non-technical knowledge to most of the educated population. You listed a ton of really infamous events, ones that are routinely covered in intro classes at all levels of schooling, and have entered even pop culture. If you think that most people are unaware of all, but a couple of them, you’re grossly underestimating people. I’d argue that the only two many people wouldn’t know are the actions of the pope one, and the Chin emperor. The rest are familiar to pretty much everyone who made it through high school.
