The core of his message is correct insofar as there does exist a rather large American-hating leftist push by many professors, with kids graduating with zero marketable skills. I mean, my favorite teacher ever was an atheist socialist philosophy prof! But that was decades ago when you could enjoy debate and not be punished for being conservative and patriotic. Today, you get socially shamed and professors are as likely to dock you grades.
I’m not sure this guy Christian has solutions, but I always err on the side of anyone who is patriotic.
