I don't think it has anything to do with being a decent person. Whether my neighbor is pro- or anti-gun, I'm not running blindly into a situation like that. I think you recently said in another thread that leaving your home is tactically disadvantageous. I think you were right.But in truth, you know that you would help them if they needed because regardless of what they think, you are a decent person.
I would do what all gun-grabbers tell you to do: call 9-1-1. If they survive the home invasion, I would offer to take them down to the gun shop and help them pick out a gun.I might not typically go guns blazing, but I can't either cower in my home and let them be victimised.
