Someone being in your house, where all sorts of things can be done to you and you don't know their intent or numbers, is one thing. But simply using deadly force to stop, say, a theft of something in your front yard or a purse snatching is both barbaric and dangerous. Now, were you to attempt to make a lawful citizens arrest and restrain them, which escalated into your defending yourself because they used force on you or came at you, then yeah use force.

We don't hang people for stealing horses anymore. People who advocate deadly force for property crimes in general really are the scourge, and thankfully the minority, of gun-rights supporters.
