I think it would take a bit more than a tug to remove a turban, the guy would be pulled about from the head quite a lot so could be considered an assault.
It's not a bad idea, in my view, for kids to be taught about different cultures which would include religions, we live in a society of different cultures and it's good to have some understanding. If only to avoid making faux pas. I remember a woman of my acquaintance mentioning 'Sikh synagogues' and my nephew coming home from school saying a teacher had talked about 'the Mohammedan church'. Cringe or what? The children at school would contribute quite well as we are a mixed society. A lot of fear and prejudice stems from ignorance.
Comparative religion doesn't float everyone's boat, I've always been interested in it which must be fairly obvious or else I wouldn't be posting here. Same no doubt applies to other posters.
