Ugh! I’ve never understood this “sincerely held religious belief” thing. Some Christians sincerely believe that all birth control are abortafecients, even though the majority of them work by interrupting ovulation. Doesn’t matter — if they believe otherwise, they can make rules affecting other people based on that.
I do quite love the flip side of the coin with The Church of the Flying Spaghetti Monster and Satanists demanding their sincerely held beliefs be honored, but it’s not enough to offset this kind of BS.
