Academic freedom is invoked here inappropriately. We need to talk about the diverse reactions students have to material. That's what the University has tried to do, to take students' reactions into account. A lot of comments are unintentional or jokey. We all say things we don't mean to say.
Most people are appalled to have offended someone.
It's not wrong to be offended, but the procedures are wrong. It's always hard to have free speech, and it's becoming even harder outside. The university might be the only place where we can have real free speech. Keep it pure.
