Your Moral Exemption is my Objection

So, how do these "moral exemption" laws work?

So, if my employer has a "moral objection" to birth control, they don't have to cover it with their benefits package, right?

Say I work for a Jehovah's Witness. Can they refuse to cover blood transfusions? How about Christian Scientists? We can just refuse all medical procedures on "moral grounds."

Moreover, isn't this tantamount to telling employees what they can and can't buy with their compensation? Health insurance IS part of any competitive compensation package, after all.

If my employer objects to alcohol, should I take up a paper route to pay for beer?

I'm confused. This all seems very arbitrary to me.
