My philosophy professor is non-religious but is otherwise a very friendly, nice, and good professor. Needless to say some of the things he says aren't totally kosher but I accept that given his religious preferences and almost all of what he says about philosophy isn't bad at all. And when he does discuss religion he tends to be correct in what he says about it, although he does get certain things wrong here and there (can't remember any good examples right now).
He was talking today about Musonius Rufus and his view that sex should only be for having kids and never for pleasure, then made a joke that it was similar to the Christian view of sex (he got a few laughs too). I'm wondering if I should confront him on the subject 1) because this is the 2nd to last class; and 2) most of what he says isn't bad even despite being non-religious. I don't think I should bother responding at this point because I don't see what it will do other than cause a stir in class.
Keep in mind also that this is a secular school. Thoughts?
[EDIT] The professor is a humorous guy who is more than capable of being humorous in class...he just cracked a joke about engineering here. So I don't think there is any malice on his part whatsoever (in fact, when I have approached him in the past on subjects like this he acknowledges the truth of the matter willingly, it's not that he believes it's wrong and wants to degrade it).
