So as a private business open to the public, I can bar minorities.When you enter someone else's property, you are a guest of their's. Which means you have said in, unsaid agreement, that you will abide with their rules upon entering. And just because the premises are open to the public, doesn't negate the fact that they are still privately owned property.
So if we have the "government" pass a law, telling essentially a business that they either will allow anyone to carry firearms onto their premise's, even if it goes against their beliefs about firearms, or that they have to spend funds to insure the safety of everyone that enters, that is okay with you?
Not for me it isn't. It's more government over-reach into my personal business, and another method of them how I will do business, and that I as business owner have no rights within my own business.
My opinion may not be the popular one here, and I'm comfortable with that, but in such instances, even though I'm a law abiding gun owner, I'll have to side with the rights of the property owner being superior in such cases, regardless of what they think or believe about guns.
