No. These children have classmate who are of all religions, to ban that garb is to tell these children "oh you have to be x to be a teacher" when some of these children are what this or that teacher is. These children are going to and are encountering these subjects/ people every day. It would be different perhaps if they had the same teacher every year (they don't) or if these teachers were saying "oh I'm this and this and oh by the way everyone who's not is going to ‘hell’". I have had teachers of a variety of different religion/ideas. All it taught me is that people are varied.

To ban a religious idea will in fact only endorse a different one- and more or less (in the USA) it would be the western/Christian ideas. To a person who is of a certain culture it is "normal" to act/wear/have x day off, to another it is not this other thing- it is in fact z that is the "norm" but then again to this third culture this x is in fact their "normal"...etc. Anyway, if the student population itself is of such varied population, it would be the most narrowing to ban any sort of garb/holiday for a teacher. We all have to live in this world.

I understand your view point. And children seeing a wide variety of religions would surely be a good thing.

It's the parents that concern me. And on occasion, it's the teachers that want to assert their religious views into the classroom.

Some parents want the belief that an invisible creature formed humans out of dirt, by hand, blew into its nose, and man was formed -- taught as science!

This doesn't help children learn how to think. Children are so impressionable. They tend to believe what older authorities tell them.

And religion, being so divisive, is hard on children. I'm not sure I want them dividing themselves so early into factions of religion.

You might be right, though. P...

You might be right, though. Perhaps seeing a lot of religious garb from differing religions would desensitize them early. But where is this place of so many religions in the same locale? (That aren't fighting each other?)
