The exact counterpart to that is something like ‘just because you’ve wilfully forsaken the all-powerful and benevolent creator of all and spit on his teachings, don’t expect me to do so, or even to refrain from trying to bring you back to the truth so you can save your soul’
I’m not religious, myself, but religious tolerance goes both ways. I’m no more of a fan of atheists who go out of their way to viciously mock Christianity (or any other religion) than I am of religious people who scream at gays that they’re vile sinners who’ll burn in hell. It’s UNCIVIL. Freedom of religion is ultimately intended to protect civil society and prevent armed conflict between people who believe different things, by allowing worshipped to worship in their own way without persecution. And it’s been pretty successful at that. Dunno why people want to mess with it.
As I said, I’m not religious. But if I was, if I REALLY believed in my heart and mind and guy that the all-powerful creator of the universe watched over us and loved us and had given us (via holy book of choice) the right way to live and the meaning of all thing, well, that’d trump any bullshit wishy washy law created by mere humans any day. And if push came to shove, I’d be lining up under Gods banner against the world with a gun in mu hand, fire in my heart, and a song in my lips.
Like I said, I’m not a believer, and I suspect that goes for many of us in here. But in our relatively low-religion times, it’s easy to forget that there are plenty of people who Believe with a capital B.
The (mostly relatively minor) legal concessions given to religions are, at heart, an acknowledgement of this. There are loads of people who prioritise the law of god over the law of man and will not be persuaded otherwise through jokes about invisible sky fairies. Tolerance of religion, and some minor bending of strict universality of law, is a measure designed to allow people to live in the nation without feeling obliged to actually combat it when it makes laws that they just can’t deal with. And usually there’s a bit of bending on both sides, like how Sikhs are allowed to carry their ceremonial dagger in situations that would get most people arrested if they carried a knife, but in exchange, the knife must be blunt.
There’s compromise on both sides.
