it isn't confusing to a child to learn that people have different beliefs. It is what can eventually make a child into a well rounded, tolerant adult who can conseptualize that someone can believe differently than he/she does and not be wrong. I wish I could explain how freeing it is to children to learn that even though Johnny believes differently, he's still okay.
Same goes here about freedom of religion, this is just a terrible judgement. Since the parents both agree on what the religion is and there isn't any conflict, what the hell is the judge doing here?
