This can a very difficult area for many students. sometimes they use inappropriate language in the class room. On the other hand they can be offended when the instructor does so. I have had students comment to me on other instructors use of rough language in the class room. The consensus (at least from the ones that I have spoken with) is that they not only find is offensive, but that they recommend other students to stay away from these instructors if at all possible. We, as instructors must always remember to conduct ourselves as professionals.
