As a person who, by choice, spent most of my life on university campuses, I retain an interest in what happens there. Generally, I have been put off by the whole campus "micro aggressions, safe spaces, trigger warnings" shtick.
Here from The Washington Post is a brief article by the President of Northwestern University defending the notion of safe spaces. I set out to read it feeling antagonistic and ended up thinking he has penned the best defense of the safe space thing I've seen. I can't promise you'll become a convert but it definitely will make you think twice.
