The primary reason my 12 year old daughter knows that religion is stupid is because we read the bible. If examined/read as one would read a biology book there is no better book than the bible in the world to show what a vile & disgusting creature YHWH is.
My concern would be that the teacher would not treat the bible as any other book. If this were the case it could be dealt with. So, hell ya! Teach that crap to my kid so I do not have to stress over it at home.
