So you call someone with guns? Defending is not the same as initiating violence. This is the difference why is not called aggression. :)

True. But non-violent is what Ghandi demonstrated the world. Respect the dignity of everyone as your own. And lead with a good example of deescalation through decisive deescalative action. And I can not remember any situation in my life, where I would have needed a weapon. So why would you want to motivate peacful communities to arm them personally?
