Thanks, Samhung, I was hoping to get some MD or PharmD opinion in here. Your response made perfect sense, but left out one of the biggest sticking points for me: what about HC professionals who will perform a procedure or dispense a drug for one patient, but not another, simply because of his "beliefs?"
The article that got me thinking about this more in depth was in the Washington Post a day or two ago. One woman was in the process of adopting a baby from Mexico, and for whatever reason, she was required to have a physical/clean bill of health. The doctor she went to was ready to perform the physical, but when he found out she needed it to adopt, and she was single, he refused, saying "a baby needs a mother and a father." Or the pharmacist who will fill a prescription for an ED drug for a married man but not a single man?
Mercurialbliss, the pharmacist in question in S2 was a roman catholic. Many, but not all, but many, roman catholics still go by the old canon "every sperm is sacred" and believe that a man should never ever shoot a load unless it is into his wife's snatch.
I'm still going out on a limb here and saying that if your conscience requires you to give preferential/discriminatory treatment, health care is not the profession for you.
