See, that's entirely backward, in my view. We have a societal system that *causes* the fear and alienation that is the root of violence. There *are* human societies that are non-violent, but the swaggering, arrogant ones appear on the scene and destroy the silence.
What would happen if we started thinking in entirely different terms now? We stop with the systems that hurt us (lame ideas like money and ownership, that are just ego constructs) and start making the requirement to give aide and assistance to those who need it. We share *all* information. It takes a very long time to get one's head around this kind of shift, so take it slowly and in small bites at first, but do let it grow and really start to see the ramifications. Everything and everyone here, just as in the rest of the universe, is all connected. We are quite literally entangled. There is no escaping that. That is a formal truth. So how do we make the best of it, because guns and defence are simply the worst in any scenario. Humanity will die out at this rate. Only the last man standing can feel safe in the kind of world we live in now, and one man is not a race of beings. He is the end of the line. What's the guarantee that he will have the qualities we hold in such high esteem - the values we cannot espouse, because of our self-induced profound fear.
It's not defence we need to preserve. We need to construct a society that encourages us to be better than we are now, and we have nowhere to go but up. We are pretty much at the bottom now, you have to admit.
Think about this for a good while before commenting.
