"I stopped talking to white people..."

Oh, okay.  A suggestion if I may, based on what I read here: stop writing ABOUT them, too.  Two reasons for the suggestion: 

1. What you write is sneering and condescending, and, based on the use of the word "I" ("I watched..."; "I recently spoke..."; "I was asked"; "I've often thought": a self-centred screed focused mostly on YOU.  I'm not particularly interested. 

2. Nothing you write here is particularly new. Nor is the phenomenon. Social commentator and author, Tom Wolfe exposed it all in 1970 in Radical Chic & Mau-Mauing the Flak Catchers, composed of two essays about the conflict between black rage and white guilt. And he did it with great perception, irony and humour.
