This tells me that students are taught to disagree with conservatives by the professors. Some are catching on, but some aren’t. Then again, I would assume that there are a certain amount of good conservative professors as well. Potential college students are perhaps not as selective as they should be when picking a college to attend.
It happens way before that. Public schools teach that disagreeing with liberalism is hate. Their parents must agree with that or they wouldn’t send them to public school.
