I think this sort of thing is a result of liberals trying to move farther left, but falling off a cliff because they have no understanding of class.
edit: I thought there was a whole thread, but to see the full context you have to go to the student's account and see the ensuing drama. This singular tweet is pretty fine on its own.
I'll be honest, even if you thought the professor was in the wrong, what did the student think he was gonna do? Just say "ah yes, you have opened my eyes, and now I will scrap the current curriculum while class has already started and formulate a completely new one based around your ideals." There's a reason why professors ask for critiques of the class after the semester is already over, it's because then they can actually make changes to them. She should've either dropped the course, or waited to give feedback at the appropriate time. Not dox the guy to her ravenous lib following.
