let's see, create a bill that allows lawsuits if a place chooses to exercise a right that has previous existed. Yeah, comply and allow firearms or have an increased risk of getting sued.
And we have businesses claiming religious grounds already, why would it be hard to believe that there are ones out there that would want to prohibit firearms because of their faith? Pharmacists don't want to give out Plan B, catholic schools don't want to cover birth control, etc.
If these signs create unsafe situations then the simpler solution is to go somewhere else. Changing the law so that they can more easily be sued doesn't change the situation these signs create by itself. They are clearly meant to pressure the business into changing its stance. It's legislative virtue signaling.
I look at it like this: Businesses have the right to restrict firearms from their premises, but they must also accept the responsibility of the safety for those disarmed citizens. And this is more than just choice of where to pick up my bread. I am typing this at Integris SW, a gun free zone, while visiting my brother. Do I uave a choice? How about those that dont have much choice?
With every right comes responsibility. Businesses ownership is no different.
