I agree....The students were not asked to defile the living Jesus (or Mohammed, Buddha or Moses), let alone their spirits or teachings. The lecture (and it's demonstration) was about symbology. At the university level, in a society that values free speech mature adults ought to be able to discuss any topic in a scholarly fashion. This student coud have told the prof, "I'm sorry, my beliefs will not allow me to participate in this experiment" and the lecturer could have said "fine, please observe the rest of the class and join in the discussion later". No "I'll take my baseball and go home" and no "you'll have to go to the principal's office. In sum, I believe, a total waste of time (except for well-paid lawyers).
