You can exercise your lack of religion. The government can’t establish a religion. But nothing says that there’s “freedom from religion”.
This is true, but I think folks get messed by separation of Church and State. It confuses many to think of freedom from religion.
Being an atheist, nothing religious ever offends me because it is all make-believe. Want to hang a cross to me it is a two sticks. Show a bible, and it is some nice fiction. Want to pray in school knock yourself out, you can't control my thoughts. I just don't like seeing people forcibly indoctrinated in it like I was by being made to go to church when I did not want to do so. But the whole I am offended by it, kills me, I believe it is a social construct nothing more. To qoute Napoleon Bonaparte, "All religions are made by men". I don't have a problem with others being religious but sometimes I voice my opinions.
Also I guarantee if a restaurant in my town announced they weren't going to serve minorities the place would be out of business before anyone could sue them
Society has a way of policing itself. I would not go to a place like that. But some of this recent stuff is different, you having politicians on both sides telling people they should be outraged. Pres. Trump has done it, Maxine Waters has done it. Let people decide themselves what to be outraged about.
I wonder how Sarah H. Sanders feels about the Supreme Court right now? I also think the owners had that right, I don't agree with their decision, but it is private property that they own. If we start excluding folks for their political views we are doomed worse than we already are folks.
