Holy crap, how can people be this dense?
If people feel that their devotion to their religion (which I think is misplaced to begin with) supercedes their responsibilities to offer adequate care to their patients, then they shouldn't be doctors. Period. A huge number of problems that the average patient population has are self-inflicted as a result of vices. That doesn't mean they can't or shouldn't get at least basic medical care.
I second Mossad -- if these kids are seriously shirking their patient-care duties, they need to be punted.
As far as Muslim doctors not seeing female patients, I actually find this view rational if a bit extreme. However, Muslims wanting to train in the West must be prepared to accept the standards for medical training and licensure here. If they cannot conscience interacting with female patients as medical students or residents, they should seek training in Muslim countries and then they can tailor their practices however they want once they are fully trained attendings.
