Well yes, actually that is the point in a way, whether you see people about to be murdered as your family. It's a spiritual concept, don't let it worry you to much.
But tactically speaking, how does it differ between your genetic tribe, and other genetic tribes? How do you protect your genetic tribe with just your "pea shooter"? If the gun's the deciding factor, your genetic tribe is dead. If, on the other hand, your will to save lives and your brains and intent to fight back matter, then even a pea shooter would work.
It's not the gun, it's the person.
Well you have a good time down at the terrorist gunfight with your Bersa .380. I have observed that the most self righteous talkers are usually the ones you see in the rear view mirror when the chips are down. :-)
