I'll ask the same question I asked in the other reply; what does "embracing Blackness" actually mean?? I'm of African descent. I have absolutely no insecurity about the colour of my skin. I didn't "embrace Blackness". At least not in the sense you seem to be advocating for. Do you also think white people need to "embrace their whiteness"? Do you really not see where this thinking leads?
Again, the key question is why you care whether Africans would win a contest of who's done more. Africa is the cradle of humanity. Go back far enough and every achievement is thanks to Africans. But so what? What is it that you think connects you especially to the achievements of Africans thousands of years ago? Or separates you from the achievements of Europeans a few centuries ago?
Western culture highlights Western achievements. This isn't surprising. You'll find the same thing if you go to Asia or Africa or Europe or Australia. All of these cultures would benefit from teaching history accurately. No argument from me. But none of them do. Mainly because "accurately" is a slippery, subjective concept when it comes to history.
But what isn't subjective is that there is no greater reason to define yourself by what the ancient Egyptians did than by what Newton did. Isn't the collectivism you're advocating for the exact same logic a member of the KKK would use to justify "white pride" or the importance of maintaining the "white race"? How is it different? How does this thinking get us to a less racist world? How does it teach our children to move past this nonsense?
Appreciate you too. This is a perspective I come across from time to time in the black community, and I really want to either understand it or stamp it out forever.
