In this case, it is a teacher taking his personal beliefs and abusing his position as a teacher to transplant his beliefs (which are repugnant, in my view) into his student's minds. This is not his job. He can hold his silly repugnant views, but why does he feel entitled, by virtue of being the only adult in the room, to feed his students his repugnant personal views?
My sister is a left-wing dingbat who wears her feelings on her sleeve, has been fired from a couple of teaching jobs and (I'd bet) at least in part because she was abusing her position as a teacher to spout left-wing ding-battery in class while serving in very conservative school districts.
