I guess I'm a little less accomodating than the teacher in this article. I believe that he should have to go through all of that (and almost whatever else gets thrown his way). People that fought for the rights of 'the other side' of his beliefs endured much much worse for a long long time. (for the record, I'm a college instructor and I would have handled this student in class just as the professor in the article did but I probably wouldn't have engaged in any conversations about his out of class activities with him at all).
The Paradox of Tolerance is an interesting problem.
