This made me think about the Christian cake bakers. A store owner could say that guns are against his religion. I think it could create a lot of unintended precedent.
If a bank bans medical masks can you sue them if you catch a cold at a bank? (for example)
You should do all your banking online or ask for special accommodations. If you knowingly follow policies and rules knowing you are putting yourself at risk, and there are alternatives, then you bear some of the responsibility if you're injured.
That's partly why I said to vote with your wallet. If you disarm yourself by choosing to go to a gun free business, that's your choice -- isn't it?
Banks are no different. Switch banks, use their online and phone services, or ask for a medical exemption for masks. Sheeple would accept the risks because they feel they have no other choice.
The Christian cake baker is a totally irrelevant situation. The reason for his gun free zone doesn't matter. Whether his reason is religion, his dog was shot in a hunting accident, his wife is a better shot than he is, or loud noises make him curl up in the fetal position, it all has the same end result: disarming his customers. He's free to have that policy in his store, but he can't get immunity from liability simply because he claims religious beliefs. He needs to get insurance and implement additional safety measures for his clientele, or he's risking losing his business if something bad happens.
It's no different than if he sprinkles holy water at the entrance to bless his customers when they enter, and someone slips on the water and gets hurt. The accident was foreseeable, and religious beliefs can't shield him from the consequences.
As for baking cakes for Gay weddings, go read the decision. He didn't prevail on the argument that he can run his business however his religious beliefs guide him. Rather, the NATURE of his cake decorating was deemed "a creative process," and he was being forced to use his creativity and skill to make a cake that supported something he did not think was right.
Making a store a gun free zone has zero to do with creativity or skill.
