I’ve seen this phenomena a lot. I honestly think it’s the contrast between personal racism which is the most vicious and violent and institutional racism where people are indoctrinated by friends., the media., prevailing attitudes.
Institutional racism is horrible but it can be overcome, often by friendship, personal experience and community spirit Personal racism is the motivator of the lynchmob
I was lucky I grew up on a small island just off Africa where we shared a house with a West Indian family for the first 6 months. Lived for years in the Caribbean. Race seemed so unimportant to us it was all about the content of someone’s character and their kindness. Many people are not so lucky
