"I'm a liberal professor, and my liberal students terrify me"

"As Northwestern University professor Laura Kipnis writes, "Emotional discomfort is [now] regarded as equivalent to material injury, and all injuries have to be remediated." Hurting a student's feelings, even in the course of instruction that is absolutely appropriate and respectful, can now get a teacher into serious trouble."

Do I do this? Reading this, and not recognizing these concerns in my science class environments - by that could be blindness on my part of my own behavior.
