I am really at a loss to understand the current state of affairs between folks of different ethnicities.
Likely because the folks of different heritage from mine with whom I grew up in a mid-size town in western Massachusetts were from intact families like mine, with lives very similar to the other folks around me. My family knew folks from as Blue Collar as my dad to a corporate VP.
Heck, my dad wasn't an activist, except his desire that everyone be treated equally well, until they earned otherwise.
When he was in USAF Tech School in southwest Texas in 1953, he sat with a friend from high school who was in his class. Dad, a man of at least 90% European ancestry, was arrested for sitting in the "Coloreds Only" section of the movie theater.
