^^Spot on. Declaring your home a gun free zone by hanging a sign (in my state) has no force of law. If you ask me to leave and I refuse then I can be arrested for trespassing but that doesn't require that I have a gun, you may just ask me to leave because I carry a condom in my pocket.
If you don't feel safe around legal gun owners then exactly who do you feel safe around?
