In CA you can refuse service as well as access, to your place of biz...( other life saving medical treatment) for pretty much any reason.
Now having a sign saying " no blacks" is going to get you in a world of hurt, but asking them to leave is fine. you are also allowed to restrict any object.(unless there is a law that says... you must wear this) for example I could make a rule that to enter my shop you have to be naked... I would just have to restrict those that can not be in that envroment( minors)
I should also point out that you still have to meet the ADA stuff and have access, but thats a civil matter... and the only real protected class these days.
Actually, I'm glad you brought this up, Tab, I have been itching all day to get home and post on this side of the discussion. Sorry,
NO corporation - from the mom & pop hardware to the mega international corporation can deny you your rights as an American citizen.
If I implement a policy that says my corporation, my division or any other part will not hire women, or blacks, or will pay them 20% less than whites, you will have a raft of state and Federal lawyers kicking your door down in no time flat. They will shut you down in a heartbeat. If I have a written policy that it is OK to embezzle from my clients' accounts, and do so, I will go to prison. IT IS ILLEGAL to do any of these. Period. No one cares that it is your own company, or that you had a policy that allowed it, it is against the law. Period. End of discussion.
So, why do you continue to believe that CCW - as in my case protected by state law (CCW) and the state Constitution (owning and bearing arms) - can be easily denied by that same corporate "policy"? Sorry, that dog don't hunt. My human rights transcend and trump a business' "rights" every damn time.
I suggest that the hysteria over guns and the lack of effective lawsuits has created an environment - on purpose IMHO (but then I am paranoid) - in which companies are allowed to get away with restricting our rights in selected areas, using a "reasonable" argument, in this case a shopkeep's corporate "rights". I would ignore a "No Guns" sign, and if discovered to be CCW, I would leave - if I in fact entered at all other to tell the owner that I would not frequesnt his store any longer.
As for big corporations - they have no rights, but they do have the law - right or wrong - on their side in most cases. Posters here are right that I can be fired for violating the "policy" if discovered. And given the climate in this country, it would be difficult to win a lawsuit against the corporation for violating my civil - or human - rights.
