In this sense, I don’t claim any sole causes for anything. I agree if you consider that foolhardy. I do think though, that once again it comes down to the Grave of Right and Wrong. One of the things implicit in a worldview that “works” invovles the idea that the sum total of your behaviors foster life: life for you, life for your habitat and nonhuman family. Abuse can happen in any context. But a mahine that runs on abuse, like our culture, cannot sustain itself. It does not foster life. Indigenously, abusive cultures could not survive. How could they? To waste energy on behaviors that do not directly contribute to the life of the family means throwing energy away. You can only do that if you have surplus energy to spare. This may mean that in indigenous contexts where a surplus of energy existed, and something trigged an abusive cultural cycle, that the community could indeed sustain it. I welcome any further thoughts you have on this - I consider it part of my job to say the crazy thing, and generalize shamelessly, when it has a use.
