I’ve had a tough time coming up with something to say that doesn’t involve screaming obscenities and yelling “no effing way…”
I have however calmed down enough to perhaps craft a message:
You cannot have my property. I will not peaceably give it to you for any reason.
Whether that is a magazine, rifle, pistol, ammunition, pocket knife, 40mm howitzer, or sharpened stick.
You cannot have my property.
