It has always amazed me how many NFOA members pretend they are against gun free zones, yet they aren't willing to get rid of the law that enforces them.
Many states, including several around Nebraska, their laws do not support no gun signs, private property owners can post them but, it's up to them to ask Individual to leave, if individual refuses, law is called and a trespass warrant could be prosecuted, just like any other behavior a business doesn't agree with. (NO NEED TO HAVE A SPECIAL LAW PROSECUTING INDIVIDUALS FOR EXERCISING A RIGHT)
First of all, I don't think it's helpful to any cause to call out NFOA members who support private property rights, and label them as being pro-Gun Free Zones. That's just simply not the case.
I would venture a guess that most of the NFOA members are conservative or libertarian; both categories hold private property rights and the right to keep and bear arms in high regard. Many believe those rights are equal in stature, and that one person's rights shouldn't trump another person's. These rights have to co-exist, and that's the point of the "no guns, no money" position (i.e. you can have your private property rights, but if you don't respect my RKBA, then I'll do business elsewhere).
Secondly, you'll be hard-pressed to find an NFOA member that doesn't think the law should be changed regarding the enforcement of posted locations. I'll bet there are very few, if any, NFOA members that believe those signs should have the force of law. I'm guessing most agree with you that a business owner should have to ask someone to leave, and that person would have to refuse before getting law enforcement involved. Then the situation would be handled as a trespass, as you mentioned in your post. I don't know where the perception comes from that people here don't agree with your position.
