Well said.
I personally believe that white skin is the Mark of Cain. The Cain and Abel story may be read as an allegory of how the early totalitarian agriculturalists took over the lands and livlihoods of the earlier pastorial people and, before them, the hunter / gatherers. Totalitarian agriculture enabled us to have food surpluses, feeding armies to take over other people's territories, to produce more food and more conquorers. Read God's curse on Cain and it reads like the history of white people. https://www.biblegateway.com/passage/?search=Genesis+4%3A11%E2%80%9316&version=HE And recall that white skin appeared in connection with the advent of totalitarian agriculture and the migrations into northern territories. (Ironically, some people say that Black skin is the Mark of Cain but I don't see how God's curse on Cain describes the history of Black people.)
Totalitarian agriculture is also the most labor intensive way of producing food and other agricultural goods. This led to caste systems and slavery. The subseqent objectification of people and lands then led to the loss of our souls.
Black people have a different history, in that sub-Saharian African people generally practiced / practice substinence agriculture, producing mixed crops, smaller surpluses, and requiring less intensive labor. So they got to keep their souls.
You're right about White people passing along racism almost like DNA. Not genetic DNA maybe, but certainly as its cultural analogy. Growing up in the Southern USA during the mid 20th century, I well remember the implicit attempts to conditoin me to be racist. These attempts didn't catch very well, because we autists don't do implicit. So they tried to explain to me in so many words why I must think of myself and people who look like me as superior. I remember. I resisted best I could yet still I sometimes catch biases bubbling up from my subconscious mind. Most white people don't remember this conditioning because it remained at the implicit level. It's very damaging, to ourselves as well as to Black people. It destroys our capacity to learn, to have compassion -- our very souls!
It's a hard pill you prescribe here, and, as I see it, a necessary one. Unfortunately, power never gives itself up willingly. I'd like to see a peaceful passing of the baton. As an outsider and a senior citizen I don't have a whole heck of a lot to lose. I see how Black people are the bigger people to put up with centuries of white supremacy with souls intact. I would venture to guess that other white folks who see the sense of what you're saying here are also outsiders. Now, to speak not to the outsiders but to the powerful people or those who aspire to power -- to ask powerful white people to step down -- that's a different story! Yet various nations have always had their turns at hegemony, rising and falling. The table has to turn again.
Blessings!
