I am missing or misunderstanding some points of your comments. I grew up as a depression ‘poor’ youth in the years before WWII. My brother,who died in the battle for Okinawa, and I played with and were teammates of boys from several ethnic backgrounds. Of special note was our relationship with “black’ people who we came to admire as a neighbor and family friends. Whether you think of such differences as not being of different ‘races’ is your take. Later in life after service in WWII including overseas I had very close relationships with Chinese and other what I called cultural groups. I never despaired about thinking/believing that in my lifetime I have had good friends from what I considered different ‘races’. My life’s experience tells me that denial of ‘race’ is like denying there was ever a Tower of Babel.
