I have not coerced anybody in that situation. They have no obligation to come onto my property - if they don't like my rules then go to another person's private property who allows guns. There is no coersion at all.
"Unless you can prove that the gunowner (who was a victim of theft) ASKED for his or her guns to be stolen, they bear NO responsibility."
Unless you can prove that a property owner asked a robber to come and shoot one of his customers or employees then the property owner should bear NO responsibility. Works both ways.
