My children attend public schools here in Texas. These are schools where the local dominant Southern Baptist population has managed to exclude Halloween from even being mentioned because it is the antithesis of their christian belief. They pray at school board meetings, they (religiously) insist on the pledge of allegiance at the beginning of every day, probably so they can get that "under god" bit in. They will insert (their) religion wherever they can, and exclude anything they see as counter to their message. So don't imagine that just because you DON'T go to a "religious" school that you're free of it.
