It was actually the Igbo tribe in Nigeria that capture members from a neighboring tribe and selling them as slaves and keeping some to use as slaves. I was reading about this lately and it reminded me of your observations. I had the opportunity to meet and chat with a. Iberian immigrant who was pro-Trump while I as a white man was vehemently anti-Trump. I bit my lip and said nothing about my disdain for him, while he showed me the indication he got to attend Trump’s inauguration because of his donation status. But it makes sense since this immigrant came from a “superior” tribe like the Igbos and couldn’t empathize with foundational black Americans. They are dominant in their own country, especially men, and over the other tribes. He and the person you describe never felt repression it occurs to me, and don’t want to. They only felt what is like being the superior group, hence he had a better understanding of Trump than I did.
