He's clearly a bell end. As a teacher he is supposed to be encouraging his pupils to achieve as much as they can. That might just involve parking some of his beliefs at home. Teacher's should not deliberately make pupils uncomfortable, nor use their profession as a religious or political pulpit. They are there to teach the curriculum.
