Then don't go in that person's house if you don't like the fact that they don't want you having a gun in their house.I understand your premise.
The concern that I have that was never really addressed,
The permit was granted for self defense of the holder.
What is to stop the owner of a property from banning a person from possessing firearms on the property and then assaulting or killing the unarmed party knowing they are unarmed? From what I understand, most killings are done by people the victim knew.
It works both ways.
What is stopping the owner of the property from sneaking up behind you and stabbing you in the back with a kitchen knife? Or hitting you in the head with a hammer from behind? Or just walking into the room with a gun and shooting you multiple times?
If someone was particularly devious and inclined to kill you, if you are willing to go into their house, having a concealed firearm on you does not make you particularly more likely to be able to defend yourself in that situation. Having a concealed firearm really only helps if the "bad guy" does not have the drop on you or does not intend to kill YOU. Or, you are there intending to kill them so you are the one getting the drop on them.
Most killings are done in a way that having a concealed firearm on you, would still give you no realistic chance to defend yourself unless you walk around with it in your hand, sleep with it in your hand, shower with it in your hand, and are alert 24x7x365.
I am pro carry, but when it comes down to it, if you trust the person so little you feel you must carry a concealed firearm into that person's house, knowing they don't want you to have a gun in their house, then you are making some really awful choices in life about who you associate with.
