I like this article by Libby Nelson on Vox, describing a recent town hall meeting Obama held in Des Moines, where he said:
It’s not just sometimes folks who are mad that colleges are too liberal that have a problem. Sometimes there are folks on college campuses who are liberal, and maybe even agree with me on a bunch of issues, who sometimes aren’t listening to the other side, and that’s a problem too. I’ve heard 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 has language that is offensive to African-Americans or somehow sends a demeaning signal towards women. I gotta tell you, I don’t agree with that either. I don’t agree that you, when you become students at colleges, have to be coddled and protected from different points of view. I think you should be able to — anybody who comes to speak to you and you disagree with, you should have an argument with ‘em. But you shouldn’t silence them by saying, "You can’t come because I'm too sensitive to hear what you have to say." That’s not the way we learn either.
I couldn't agree more with Obama here. There's no benefit to shuttering yourself off from the world and forcing everyone around you to adhere to a strict standard of behaviorial sterility. To try and insulate yourself and everyone else from any type of offense inevitably leaves you ill-prepared for the realities of the world. Not to mention it would also make life incredibly boring. I don't know why anyone would want to close themselves off to different perspectives and ideas they disagree with.
