I don’t know if I agree with everything your saying. Like this alleged quote from Rav Yaakov ZT”L. The people in power in the US were treated blacks like inferior sub-humans, which is the exact thing you said should not be done. That’s what MLK et al were fighting against.
What needs to be said is that the Torah concept of Goyim and Umos is completely incompatible with whatever the modern day concept of race and racism is.
One thing I feel that needs to be said, that will probably make a lot of people angry at me, is that in the frum community racism is unfortunately very common. People tend to look down at goyim (and even Yidden) because of the color of their skin or the shape of their eyes. They are spoken about as if they are little more than beheimos. This is a huge endemic problem that must be addressed.
Finally, let’s talk about Critical Race Theory (oh no I said the thing!). The main idea behind it isn’t that white people should always feel bad about racism or whatever. What it means is that even once racism basically became illegal in the US, the same people who were previously praising Hitler Y”Sh for his “ubermenschen” were still running the governments, universities, banks, and schools. So they snuck in a lot of policies designed to discriminate against black, Jews, immigrants, and other minorities. The Long Island overpass is probably one you’ve heard of. When designing the Long Island Expressway, the engineers wanted to make it difficult for black people to come in from Manhattan to use the beaches. The eastern part of Long Island was very white and most blacks were coming in via charted buses from Mid Town and The Bronx. So they designed the bridges to be too low for buses. This type of policy was mainstream in many many hidden (and not so hidden) ways. From jobs to bank loans to education. Skin color isn’t as easy as changing from Chaim to Hyman and putting on a baseball cap over your yarmulka. And a lot of those policies still exist in many forms.
