“We are a secular nation, not Christian (anymore) and at some point will probably be muslim”

“A precedent of limiting coverage on religious grounds is dangerous grounds to be on?”
Why? Do you imagine employers won’t let their staff buy condoms, receive blood transfusions, or whatever else superstition forbids? There’s an elegant solution, and one our civilization gas apparently forgotten: get another job! Better yet, let’s decide as a society to divorce the corrupt union of employment and insurance coverage.
Oh, you mean the IRS.
