Conservative parents need to look closely at the schools their kids want to attend. My son tells me repeatedly how his professors promote Clinton for president. He repeatedly speaks up in class and says he doesn't believe a class on video media should even be discussing politics. Perhaps because I remind him everyday that his professors work for him are responsible for providing education on the subject/topic he has paid the professor to teach. Thank God when I attended college in the 70's I didn't have to deal with this. But I can tell you I wouldn't have took it sitting down.
To be adversarial, I'm sure there are some instructors who promote a Conservative for President at some colleges.
