None. All religions (Christianity, Islam, ect) should be taught as works of fiction as opposed to historical fact

It is for the individual to make their own decisions. You teach them as stories. That is what they are. It isn't a teachers job to determine for children if they need faith in a higher power on not. Nonsense question. They are taught as someone else's belief, not if it's fiction or not. As stories they are mostly fiction yes, but the use of old text is to learn from it's lessons. If a teacher cannot grasp this then they are not a teacher, who would teach something so old as fact? We do not know. Jeez.
