One was in the hard sciences, the other was in English and to tell the truth, I had no idea what their politics were and still couldn't tell you today. WHY? Because they actually taught their subject, never ever introduced any, not even a hint of, politics of any kind, into their lectures nor exams. It was just facts, facts, and yet more facts...devoid of any opinion.
I was lucky to have had them as profs; they were two of the best teachers I had in college and grad school. And I'm glad that I went to school before the lefty indoctrination went into invade every level of education.
Note, it’s the professors of education that are the problem. Teachers College at Columbia is the problem. They are committed to progressive theory and the ghost of John Dewey.
