Birdy, I cant help but feel that your arguing with yourself. No one here is saying christianity shouldnt have been part of the lecture. All anyone is trying to say is that in a situation like this, the teacher should not preach to the students. Since neither you nor I know the student or the teacher personally, it is completely irrelevant to say we believe one over the other. It has nothing to do with the actual issue and merely convolutes the argument to the point that its at now.
