@Cheri @jayeless Jayeless' post and the one Cheri linked to put me in mind of something that happened at the college where I teach. This was a long time ago, so I don't remember the details. A student in a composition class taught by a Jewish professor wrote an essay espousing Nazi ideology. As I remember it, the professor did not want to have to grade the essay, for obvious reasons, nor did she--I think the prof was a woman--want the student in her class, also for obvious reasons. I don't remember what the outcome was, but I have often wondered what I would do in the various ways that situation might have played out.
