He then asked if I was willing to shoot someone over my xbox.
I told him, "The xbox was besides the point. We are talking about a person intruding into my house at night with my family present. Hell yes, I'd shoot him. It's the principle of the thing. I'd shoot a hole in my xbox without blinking to do it."
Well said - and, Leftists sincerely don't believe this ever happens, and when you give them any concrete examples (the Wichita Horror, just for one), they just assume you're either lying or just being dramatic / paranoid - and they certainly don't believe this kind of thing has ever been prevented by homeowners with a gun.
Heck, homeowners with a dog have prevented mass murders. Literally any resistance is enough to dissuade most opportunistic burglary. Planned burglary while the residents are clearly home is a different category all together.
There was some serial killer I recall reading about that would just move on if the door was locked. He felt that if your door was unlocked you were inviting him inside to kill you as some sort of elaborate assisted suicide.
Let them be the ones to leave their doors unlocked. And a big sign "Gun-Free Household" and "BLM" and a rainbow flag to show how woke they are.
