Point taken, but the other side of the equation is that the "management" (probably a twenty-something kid - maybe even a teenager) would be in the uncomfortable position of approaching the posturing AK-laden boob Not the king of thing a 20-something manager (or whomevers on duty) may feel up to doing, for fear of a confrontation. Or dealing with the mess of calling the police to ask the boob to leave. So corporate ducked the entire question, banning OC.
But, still, a meaningless corporate statement unless actually posted, right?
Philosophically, i think part of the underlying discussion here seems to touch upon the treatment of the second amendment as a civil right (equal protection regardless of race, gender, national origin, color, sexual orientation, ethnicity, religion, or disability) versus the 2A as an individual right (along with freedom of speech, etc.).
A business (even as a place of public accommodation like a restaurant like Whataburger) would be in deep if they discriminated against the civil rights of folks (refusal to serve based on race, gender, etc...).
But, such a place has a lot more latitude in not honoring individual rights ... they can more readily restrict certain types of conduct on their premises.
Like it or note, OC is a polarizing topic right now for businesses. They have no interest in being dragged into the debate, pro or con. It's the posturing boobs - on BOTH sides of the debate - that have created an environment that businesses just don't want to deal with. It's hard enough to keep a business afloat without folks abusing their 1A and 2A rights.
