I express a lot of points of view in my classroom, and I let students tape everything I say. (As a matter of courtesy, I think a student should ask first.) Why say something to a roomful of people if you wish to hide it?
Sir, iot is so obvious that you are a conservative, and NOT a liberal prof who wants to censor other opinions while protecting your own desire to indoctrinate students. Bravo for you. I hope that you soon get tenured and continue to practice true academic freedom. The Lib profs definitely do NOT think like you.
