"F" them with a stick! It's your house, not there's. I would INCREASE the gun and gun literature material. Do you have a Galco Model Miami Classic for your favorite pistol?.....Get one, and open carry around the house while wearing a dirty wife beater. That ought to shut the bastards up!
Instead of network prime time, I would put the DVD "Complete Glock" by Lenny Magill on at 7:00 PM. If they leave, what are you out?
