No, Kim Davis is not being jailed for her religious beliefs, she’s being jailed for refusing to follow the law. She is free to refuse to enter a gay marriage, but she’s not free to deny anyone else what they’re legally entitled to under the law.
Any religious right wingers who don’t understand that, I would ask them to consider how they’d react to a Quaker clerk refusing to grant gun permits because of his pacifist religious beliefs. Or a Buddhist food inspector refusing to okay meat at grocery stores because of her religious beliefs. Or a Satanist refusing to grant a building permit to a Christian church. Get the picture yet?
