Can convocations be controversial?

In a review of the convocation program’s goal of including diverse perspectives, it has been noted that there is a general lack of politically conservative viewpoints. Other colleges and universities have attracted media attention when the presence of conservative speakers has resulted in student protests. An article in the September 15, 2015 issue of the Washington Post reported on comments made by President Barack Obama at an education town hall in Des Moines, Iowa. He waded into the discussion over political dialogue on college campuses, arguing that students should not be "coddled" from opposing political viewpoints:

I’ve heard of some college campuses where they don’t want to have a guest speaker who is too conservative, or they don’t want to read a book if it had language that is offensive to African Americans or somehow sends a demeaning signal towards women. I’ve got to tell you, I don’t agree with that either — that you, when you become students at colleges, you have to be coddled and protected from different points of view. Anybody who comes to speak to you and you disagree with, you should have an argument with them, but you shouldn’t silence them by saying you can’t come because I’m too sensitive to hear what you have to say.

Ideas need not be popular, palatable or even easy to digest to merit discussion. College is a place where ideas of all kinds should be openly explored.
