When pulling back and looking at your statement from a thousand foot view, your question can go either way.
'Morally correct' is a loaded question. Morally correct that a religion would let you go with out a nutritious meal? or a soup kitchen providing free meals that someone won't partake out of an edict that has no foundation in modern nutrition science. Just because some one 1700 years ago said 'not to'.
I question both parties motives here. You have to realize that even religion has motives. Is the entire medical society and pharma bigoted toward Scientology? Or are Scientologist making a choice?
I think I already clarified my position on the morally correctness of refusing a meal when you're hungry. If you have nothing and somebody gives you something, then you should take it. And I feel quite strongly that there were probably muslims who were and maybe still are eating at that soup kitchen.
It's not religion itself that has motives, in my opinion, but the people who use and/or twist religion to their own liking that have the ulterior motives. Case in point, there is nothing wrong with Scientology having tenets around silent birth and infant care (if you're not a member, you can choose not to follow), but there's a lot wrong with somebody like Tom Cruise going on national television and specifically calling out other people for being bad parents b/c they don't follow the same tenets that he follows.
