> Similarly NRA wouldn't care if you got kicked out of a movie theater for being concealed carry, but if a local city tries to ban guns in movie theaters, then NRA would step in.

Well, this isn't entirely accurate. They definitely do chafe at even private restrictions on anything gun. While I don't have time to research this right now, a quick search of "concealed carry in businesses" certainly returns some people complaining that businesses shouldn't be allowed to restrict that. And, if you dug a little deeper, I imagine the NRA would be weighing in there somewhere.
