Honestly, this argument comes across to me as a horrible mangling of different pop-sci concepts to construct a victimology. There’s good evidence of the mechanism by which stress and trauma induce epigenetic changes in organisms. (Selective methylization regulating expression of genes.) There’s some evidence of epigenetic changes due to physiological trauma passed down through germ cells. But it’s a huge leap to ascribe mtDNA damage to psychological experiences.
The mitochondria have a degenerate genome, a tiny amount of DNA with (looking it up) 37 genes to support the processing of energy into ATP to power the cell. It is susceptible to epigenetic changes, which leads pretty directly to a number of metabolic disorders, but I can’t find any evidence that those changes result from life experiences of an animal. The idea that mtDNA has accumulated generations of damage from sexist trauma beggars logic, too, because there’s just not a lot of room to collect damage, and that damage leads to health problems fairly directly. If one got every cell of life from one’s mother, in turn, she got it from her mother, and so on all the way back to the first eukaryotic life. All of those generations of trauma, how are we even still living?
Furthermore, the assertion that “men created the patriarchy” ignores actual history and context. One simply cannot ascribe a singular intent to a class comprising billions of individuals across time and space. At best, one could describe patriarchy as an emergent phenomena of societies and cultures. About half of the individuals in those societies and cultures were women, so you’d have to conclude that women helped create patriarchy, unless you deny their agency or intelligence.
I’d say that 20-50 years is generous. Maybe if they’d won every election, but that’s now how US politics goes. When one side stages a coup, and history shows they’re going to win an election again within the next cycle or two, not throwing the leaders of the coup in Gitmo by January 21, 2021, at the latest, sure seems like enabling fascism.
