In response to Post 5, I had a standing rule with students that I wouldn't discuss my positions on either religion or politics. But it wasn't because of parents, school boards or administrators. It was because I had a bully pulpit, some kids (astonishingly) looked at me as someone whose opinion mattered, and I didn't want to make kids who held different beliefs to feel uncomfortable. I would break that rule sometimes with seniors, but as a general rule, I was very careful about such things. But more generally, teaching is inherently a subjective pursuit, as it involves dealing with dozens of kids who have different needs and learning styles.
