I don't worry to much about this. I know between myself, and the select few that I trust to group up with in the event of SHTF, we'll have a few of everything.
As I've said to a few idiots who are anti gunners, I have enough weapons to protect myself for some time, I'd be in short supply of trigger fingers. That's when they say, See, we can just come over here and help you out and supply trigger fingers. That's about the time I tell them, STFU, you'll be locked out. You talk all this anti gun shit, but you want to come here for protection when and if SHTF??? You can go to hell. I'll want people that KNOW what they're doing and that I don't have to worry about accidently shooting me in the back, that if you don't use firearms and practice gun safety in the real world in a controlled non hostile environment, you damn sure can't do it in a hostile environment and you'd be more of a danger and liability to me and my family than you would help. Suprisingly enough, they tend to mumble a bit and shut up.
