I worked at a hospital a few years back where they brought in this boy who desperately needed open heart surgery or he would surely die. Problem was that Mom and Dad were Jehova's Witnesses' who are virulently opposed to any kind of blood transfusion.
Well, the boy would have lost too much blood without donated blood of his type on hand. They refused, citing some obscure, completely misinterpreted passage of the bible and thus following some invented rule for God's sake in the absence of God.
The boy died and rage spread throughout the hospital because it wasn't that the doctors did the best for him and he simply died anyway, it was that it was totally preventable in the first place. That boy could have easily lived.
Anger also spread because in the eyes of the law, religion is an almost untouchable thing, so sacred that no single human may usurp its authority. I believe in the establishment clause advocating the separation of church and state, but clearly some people do not understand what it means.
All that thing says is that they will not infringe upon the other and that no special status will be given to any religion. That's the gist. The simplified, layman's version isn't much more simple than defining it legally.
What it sure as shit doesn't mean is that radical Muslims can "practice" their Jihad on thousands of unsuspecting civilians. It doesn't mean that Navajo's can take a shitload of Peyote off their reservation. It doesn't mean that practitioners of Santa Ria can decapitate chickens and sprinkle its blood all over your doorstep to either ward off or summon evil spirits. And it doesn't mean that because little Jimmy's parents are Jehova's Witnesses that the doctors can't actually help him.
Guess what??? Did you know that it has nothing to do with the freedom of religion, either this case or the one stated in the OP? It has to do with the fact that the child was a minor.
No one can legally do a thing to child without the expressed permission of their parents. That is only negated when the parents are abusive and so lose their custodial or guardianship rights to the minor.
The best and most appropriate question for this thread is: What constitutes abuse and where should the line begin and end with parental rights versus government welfare rights?
