I am willing to believe that most college professors are merely liberal, and not flat-out dangerous crazies. I do wonder where the point comes that the responsible ones do not just try to be good examples, or make reasonable statements, but to outright condemn those who encourage violence, directly or indirectly.
I see two difficulties. I suspect that absent a significant unity across departments at a single university, most faculty does not have much influence outside their own field, and it is entire fields which seem to have gone mad, so we cannot expect any serious condemnation from those. Secondly, administrators seem to be a large part of the problem, and they are differently-answerable. Professional pride of trying to discern truth and teach independent thought and problem solving are not really part of their job description. They may have these things in their value system, but they aren't required. What is required for deans of this or that is to defend particular ideas or groups of students.
Oh. No. Wait. Social workers and other mental health professionals have crazy and dangerous ideas that they make public and I don't do a damned thing about that. Never mind.
