Kerfuffle in Class

I don’t think I understand. Was the language of Professor Lawrence Rosen quoted in “Classroom Clash” (On the Campus, March 21) — without endorsement of any unacceptable labels as far as I could tell — the only language that caused students to walk out and launched the kerfuffle? I thought teachers were supposed to ask questions and use examples. Have the political-correctness police become so dominant that faculty can’t do that at Princeton anymore? That’s not the Princeton I attended or to which I would want to send my grandchildren. And how did the students who were so shocked ever make it through high school, much less attend a major university?
