I was about to post the same thing.
There’s no such thing as a gun free zone if I’m around.
A private company disallowing weapons is not a 2nd Amendment issue. Just like a business owner telling you that you cannot wear a MAGA hat is not a 1st Amendment issue.
You have no rights to enter private property. You especially have no right to enter private property against the owners wishes or enter in a manner contrary to their conditions for entry.
I comply with the signs out of my profound respect for private property rights. If I decide to keep you off of my property until you disarm you can either disarm or stay out your choice. But what wont happen is that you enter armed against my wishes.
Got a news flash for you here too - after the El Paso Walmart incident, there has been a sudden uptick in the normal loss prevention anti-shoplifting panels flanking the doors being replaced with walk through security arches that contain magnetometers and anti-shoplift sensors.
