There's an idea taking root on college campuses that students cannot be exposed to any ideas, words or phrases that discomfort them in any way, even if that wasn't anyone's intent.
That's why schools are embracing "trigger warnings" — warnings placed at the top of readings that mention a topic that might "trigger" a flashback to some awful episode in a student's life. One law student at Harvard went so far as to request that the school not teach rape law because hearing about that crime might re-traumatize anyone who lived through it.
