Sadly the current transient politically correct fashion for “safe spaces” has resulted in a situation where it doesn’t matter how assiduously the teacher attempts to provide a humane learning environment because nowadays entire fields of study have been deemed “unsafe.” Just imagine if you read something in a book that mentioned the Holocaust or Stalin’s gulags or Mao’s insane Cultural Revolution! Just imagine if you heard something in a lecture that contradicted your own ignorant beliefs!

When we try hard enough we can ensure that no space is safe, and then we can all feel wonderfully self-righteous about our unwillingness to entertain even a hint of reality.
