and everyone returns them as they leave.

I mean, what could possibly go wrong?

who are against oppressive
over-regulations on businesses?
Bullshit.

I will not go to the movies if there are guns , I can stay home and shop on line, I cam watch movies at home, I can make my own Starbucks coffee. The gun nuts can go to hell

but are willing to shred the first. What a bunch of little chickenshits.

Take out those metal detectors and relieve those security personnel!

soon there will be businesses with gun/no gun signs in the window or rainbow/no rainbow signs or crosses/coexist signs and we can choose where to spend our money

Expect more and more of these silly proposals as the GOPers seek to destroy Carthage, and as politically tone-deaf Democrats mumble about more gun control. To the Republicans, gun control is the gift what keeps on giving.

the legislature also passes another law allowing unarmed citizens to sue the NRA when a formerly "law-abiding gun owner" commits a crime with a gun.

1) Society has become entirely too litigious. The answer to mishaps, crimes and losses of every sort is not always a lawsuit.
2) Sue the venue if their restrictions are unreasonable; show their actions and/or lack thereof have materially contributed to your loss and sue on that basis. Venues are, in general, no more to blame for losses, injuries and deaths from shootings than the manufacturers of the guns used.
3) I'm not sure what the NRA is thinking. I don't see how this advances the RKBA.

I, for one, agree with the 'vote with your money' stand.
Whether you're pro-control or pro-RKBA, don't patronize establishments with which you disagree.
A new law isn't needed.

I am sure they take further steps besides just banning concealed carry weapons.

Just the act of banning is all the "security" they will probably take.

criminal acts committed with a stolen gun; this seems to be the pro-RKBA analog to that. In either case, I wouldn't support holding a third party liable for the deliberate criminal acts of another.

Businesses (and other private properties) should be allowed to set rules for what gets brought inside their establishments, and patrons/guests are free to stay away if they don't like or don't feel safe with those rules...
