It does if there's nowhere else to go. Really, how many time does it have to be pointed out that we've played this game before and it really, really wasn't pretty?
History. It works, bitches!
Let's try a thought exercise: Man is shot. Needs a blood transfusion, but the only available doctors/nurses/janitors who aren't afraid of needles are Jehovah's Witnesses, who don't believe in that. They refuse to perform the transfusion on religious grounds. Then is it harmful to allow someone's religious proclivities to dictate their work ethic? Any reasonable person would, I think, quite well tell the doctor to nut up and do his goddamned job and save the patient.
