If the local cinema is so dangerous you think you might need a gun there, you should consider not going.
Seriously, what kind of person thinks any and every public gathering is dangerous enough to rate carrying a gun? Unfortunately, millions of people think exactly that. I suspect they don’t really believe it: Their paranoia is a rationalization for the psycho-sexual power thrill and reinforcement they gain from packing heat. I really think all gun humper justifications are like that; just rationales.
