Having been in classes in very liberal institutions in the last decade, I can guarantee that not only did that instructor dismiss this student’s challenge, he/she went out of their way to ridicule this student.
I had one class, world geography, where the instructor produced climate change propaganda for every section. When I would challenge him and show him the “follow-up” articles that outright contradicted what he provided, he would change the subject then close the discussion so I couldn’t respond.
Liberalism at it’s finest. When an entire generation of liberals took over academia, the resulting problems in the world were not hard to predict. Which is why the 1936 Communist Goals put such emphasis on doing that very thing.
The most insidious part is that the kids taught by the libs simply don’t have the tools to see the indoctrination for what it is...because...
They were specifically taught to NOT have that tool in the toolbox.
