I like this part the most:

"There was clear desire and reason to capitalize Black. Most notably, people who are Black have strong historical and cultural commonalities, even if they are from different parts of the world and even if they now live in different parts of the world. That includes the shared experience of discrimination due solely to the color of one’s skin."

Because you have identified skin color as important for the second-largest continent on earth, but white people, being the minority people when considered on a global scale, are too dissimilar across the same spectrum.

HONK HONK!
