I agree with you but I have a few things to say on this.
Actually even the notion that blacks have been more oppressed is not even accurate. If you go to the Middle-East there have been areas where whites have been cruelly mistreated by many races, blacks included. Jews obviously had the Holocaust costing them 6 million lives (one third of Hitler’s death toll), and Stalin (though he was white himself) oppressed millions and killed 20 million of his own people. Mao oppressed his own people, killing 65 million. There’s mistreatment all over the spectrum, and it’s never been about what skin color everyone is, but who has the power. Evil people in power don’t have to care about race, or anything. They’re just evil. In America the people in power were white people for a long time, but all slave owners weren’t white. (The other thing is that only 1.4% of whites were slave owners, meaning they weren’t all as racist as we might think). There were many native american slave owners, and yes - black slave owners. Did you know Kamala Harris’ grandfather was a black slave owner? Because slavery wasn’t about race - it was about who had the most money. Rich blacks were not slaves - they were owners. Yes, a majority of slave owners were white, but to think of slavery as a “white” institution is inaccurate.
Asians have also been oppressed pretty badly but I think people will quiet down on that one more because asians are far more successful than blacks (and even most whites) and if they both have been oppressed then the question is why is one doing well when the other isn’t, and people don’t want to answer that question because it would actually make blacks accountable for something instead of allowing them to hide behind the “white man held me down 50 years ago before I was born” argument (bc seriously there’s so many 20 year olds talking about how they get no opportunity these days). People will talk about asian oppression when trying to condemn white supremacy and then they suddenly care about Asians but it’s always been clear that Asians don’t matter to the left as much as blacks do. Blacks are allowed to be completely racist to Asians (and any other race) without any problem, but asians can’t be racist to blacks.
The race spectrum is not what everyone thinks because it’s been manipulated to fit narratives.
