I think we can pick one story and show one thing, and then another one to show another thing. Or hell, pick the first one again to say something different than the first time.
History is a malleable thing, and what you base your argument on is a version of it, not sure it's the truth.
But the gist of what you are saying is that any people would have done what White folks did. Just give them time.
You know, I don't believe that. White folks were exceptionally OK with genocide, we always have been. Intergenerational traum, I guess, from the millenias of tragedy of the Continent.
To presume that our white trajectory is the necessary trajectory for ALL PEOPLES, because 'ecology' (which is a scholarly discipline defined by who, may I ask) is.... BONKERS.
I'm sorry, I am sure you are bright and you seem well-read and intelligent but the idea you propose as an infallibility for all humans is completely and utterly bonkers.
The non-voters had nothing to do with this. They literally did not participate.
Any real democracy would count the non-voters as part of the results. 20M not voting? OK then, any policies that affect everyone can no longer be enacted. No new laws. No new wars. Government can then maintain plumbing and provide public services, that's it.
Why isn't that the case? Why is it not a requirement for people to vote for government to have power?
Democracy...? Sure. Whatever hope you need to feel, friend, see you in the streets I hope.
