That, loosely, is the perspective of Psychology Today's conservative social psychologist, Robert D. Mather.
I agree with the Heterodox Academy that such a watchlist does not facilitate collegial discourse. Indeed, this watchlist is a response to events such as the bias response teams and trigger warnings that have covered many campuses and predominantly silenced conservative but not liberal discourse. For conservative students, speaking in class already registers you on the informal watchlist in the predominantly liberal academy. For conservative professors, offering their perspective does the same. The idea of a watchlist is similar to the informal blacklisting that occurs for conservative faculty. While there may be unpleasant implications of a Professor Watchlist for liberal professors who stifle viewpoint diversity, free speech is a double edged sword and conservative professors have felt the sharp edge of blacklisted ideology for many years.Or, perhaps, it's simple unfamiliarity with the counter arguments that leads to Tenured Radicals Behaving Badly. I'll give Rod Dreher the final words. "The fact that Professor Watchlist exists, and that there is an actual need for it, is evidence of a profound institutional failure, and a failure of trust." He backs that up, with additional evidence and commentary. Do go there.
