What about humans hunting humans for small green slips of paper that can be exchanged for food? Here and now, let alone in a "survival" situation?

In my not so humble opinion, anyone that refuses the notion of using firearms--whether personally using them, or allowing others to do so--is deluding themselves to the veracity of the Golden Rule.

I like to call it the "Godless Rule": Do unto others before they do unto you.
