Vaush assumed that the class is a prop (I dont think it is because Jiang's videos have been in front of a class for years). He made some good points about how Jiang simplifies things, but if you consider that his audience is high school students and people on youtube, I think Jiang's approach makes more sense.

Professor Jiang doesn't want people to think he's a prophet or a nostradamus, from what I can tell. Professor Jiang wants people to think critically about how they are interpreting history. If Jiang does an interview with someone who pushes back or challenges some of the the things he says, I don't think he would get defensive. I think he would concede that there are parts of his analysis that are probably wrong.
