You've said elsewhere that you'd be concerned if a teacher were a facist - would you not mind if they were teaching to the cirriculum at school, but in their time off work publically promoting fascist material? I don't mean to conflate the two subjects (fascism and pornography), but just point out that we don't (and shouldn't) judge teachers just on what they do at school. Of course, then it becomes a question of what is and isn't acceptable for a teacher to be doing in public outside of work, and I don't think its moral panic to say that pornography is not acceptable - sex education and teaching about relationships is very sensitive as a subject for people because as I've said there's a great potential for harm and exploitation.

We should assume good faith until demonstrated otherwise of course. You don't think your pepsi coke thing was silly?
