I don't really understand what you are saying but I will say that I don't think minorities suppressed themselves in the past or that Uighur people for example are suppressing themselves. In a way China is doing it to itself yes, but one group is distinctly responsible inside China and one is victim. The same can't be said about climate change or it's consequences.
People, minority or majority, kill and torture and otherwise harm people. That's the easiest way of looking at it without any ideological filter. It's the truthful starting position. After which you can say the Chinese did this to the Uighers, or this majority, whether Han Chinese, or whatever national-majority, did this, to whatever national-ethnic-minority. These are aposteriori ideological considerations. The primary point, that people do this to themselves, never goes away. We thus do it to each other, over time, and it comes back to bite you.
Call it Karma or common sense: cagers shall be caged. That's a karmic principle, secular, as it were. The Slave-holders in the Southern American colonies internalized a slave-master-slave dichotomy. That is, without going to pyschological, you can see sociologically the fallout of successive generations which in the United States still deal with the legacy of slavery to Jim Crow segregration, living memory, and it is worse in the South where the Confederate flag remains a symbol of division precisely for the general reasons outlined above. Are white people arguing amongst themselves? Or are they arguing with their non-white neighbours? That is what I mean by doing these things to ourselves for you must live within a society and the desire/whatever it is to trap, hurt, harm, maim people, or enslave, comes back, even if it takes a hundred years (or ten or twenty, why count) to bite everyone involved. It was biting them during slavery: thus the North/South divide in the first instance and abolitionists as well as during the Civil Rights period:
"The murders of Chaney, Goodman, and Schwerner, also known as the Freedom Summer murders, the Mississippi
civil rights workers' murders, or the Mississippi Burning murders, refers to events in which three activists were abducted and murdered in the city of Philadelphia, Mississippi, in June 1964 during the
Civil Rights Movement."
All people are murdering all people, implicitly or explicitly. That is the world within which we live and the one which we leave. Climate change, wrought by spasmodic lack of planning over decades as well as deceit and disinformation, but general economic illiteracy, whether capital-ism or commun-ism, is merely the meta frame for all the world's ills which are contained within it on a day-to-day basis and which frame, macro, if you like, reinforces all of those worst instincts and passions and they will, without intervention, erupt.
Now, all people are doing this to all people. It is only people involved here. Genocides, cultural or literal or whatever, will only worsen: as the economy of the climate worsens, the climate of the economy worsens. So it is a myopic mistake of reason to treat resource scarcity/worsening temperatures/migratory patterns/(see treatment of migrants)/and so on as anything but directly related to and driving the very genocides and miseries we consider remote from climate change.
The world runs and has run upon a war-economic footing for centuries. The military industrial complex, "new in the American Experience", said Eisenhower. He was referring to something rather old in world experience. That is in many ways the root cause of all the problems we now face in one go. Spasmodic hegemonic attempts, with zero planning beyond this nation advances here in reaction to that one retreating there, to make the world in the image of any given race, nation, person, or ethnicity. That needs to end or the world itself is done before climate change gets out the door. The cascading effects will get there first. Simultaneous transition, thus Bretton Woods 2.0, from War-Economy proper, to Defense Economy wherein Climate is treated (and not just climate) as a defense issue and thus funding allocated accordingly. There is no other means of solving this for we do not have two trillion to spend globally on war-economy which fragments global climate consensus in the first place and then try and piss, literally, in the wind with bandages and call them solutions. Seven years to get it done, and I would say about seven months to see serious progress which will decide that seven years (which seven years will decide what we call, weirdly, the "human experiment - or, Have we ever been Human?" - so far the jury is out).
