From an essay in Inside Higher Ed about the bullies on college campuses who enforce conformity and try to silence ideas:
Enough already. Just as the only thing necessary for the triumph of evil is for good men (and women) to do nothing, as Burke taught us, the only thing necessary for the triumph of censorship is for the rest of us to keep quiet. Speak up, people. Our freedom of speech depends on it.
The rest of it is here.
