Fair points and I tend to agree with you. As for Conservatives (or any reasonable, civil speaker) being banned from campuses, threatened, or protested so violently that they're effectively banned, it's ridiculous and harmful. A speaker advocating for something virtually everyone knows is wrong such as burning churches, molesting children, terrorism, etc. is understandable, but making it impossible for someone who has a reasonable but different view is so counter to what our nation stands for and the principles of free speech, tolerance of different viewpoints, and the idea of just educating yourself about all aspects of an issue.
When a young person goes off to college, a huge part of their education takes place outside of the classroom. It's being exposed to other ideas, stepping outside their narrow view of the world, hearing other viewpoints, being forced to examine new ideas and compare their own beliefs with them and then either defend their beliefs or come to understand that other ideas may, in fact, be more correct. The insulated, "I'm not going to listen to anyone who has a different view" crowd on many of today's campuses are missing out on that aspect of their education, intellectual growth, becoming well-rounded, and process of maturing.
