Wow, thanks much for sharing your excellent story and background. Very interesting personal history. My father grew up in Newark. His father, my grandfather, was a judge and engineer, and after WWII he was the first white man to sell houses to black Americans in Newark.

I don't have a specific reason to capitalize black or white, but it seems Germanic and unnecessary. Ultimately there is no clear line or distinctions between skin colors, with species differentiation marked by the inability to interbreed. We know humans can interbreed no matter what the skin color to produce a human, so there is an articificiality to using capital letters to fossilize a mental difference marker that doesn't biologically exist and only serves as a way of repression.

Capitialization of nouns in normal in German, which I studied and visited, but such formalization in English serves to make a point, and the point here is to use language to draw a primary difference between "races" which we now know for certain does not exist. This racial maintenance distinction has allowed attributes to be attached to the different "races" and the key mental mechanism that allows for simlilarity blindness.

I don't like to have mental barriers that prevent me from exploring new ideas and mimicking outdated socialized patterns of capitalization that were most likely derived from aryan association of Germanic characteristics should be thrown aside. Just my two cents becasue you asked. Thanks again for the great dialogue.
