Well, to be honest, I am saying they should, but I am not happy about it
It creates an unpleasant dynamic that I'd rather avoid, but the reality of property rights of a business owner compels me to say that as an owner of a business, why shouldn't I have such a right?
Is it wise to exercise such a right and create yet another dangerous "gun free zone"? Well, that's another issue...
My frosty libertarian side says that owners have rights too... My crispy 2A side says F-OFF
