The changes you seek as expressed in your post are generational changes. The kind of society you envision in your post requires generations of effort to establish peace. For some people, that kind of thinking is actually a way of life, not just a philosophy or a principle to follow.
Yes I am aware of this. I believe I said it is my goal but, would likely happen after I am no longer alive.
As to the rest. I've already been walking that path you described for some time.
I only recently realized that while I am walking it that the masses walking the other direction seem to be mobilizing. Sure aggressive forces will meet, they will die out, and eventually we will have peace. That is a given cycle.
Yet, does that mean I should ignore it and potentially be caught up in it, and left as one of the corpses in the aftermath, whether I was peaceful or naught?
NAP is not pacifism. It does believe in Self Defense and I have pretty much only focused on localizing my views of it. To my local area and what I perceive physically near me or others, and to my speech as you have indicated.
Though I am starting to see NAP may be a bit larger than just localization. See @cupidzero's comment. I think he made a much better write up in his response to me than I could do myself.
