Btw, for what it's worth, let me reiterate my book concept:
I am editing a book of a very small number of my Mudcat posts on the specific subjects of Black culture (including my childhood, teenage, and college memories; my Baptist church experiences, and other experiences, as well as my posts on banjos, spirituals, children's playground rhymes. Included in that book will be a very small number of my Mudcat posts on race & racism. The book will include a significant number of anecdotes. There will be rather lighthearted comments and rather heavy duty comments. But there will not be any scholarly research. That is not the stated intention of this book. I don't have the expertise for that. I'm just an armchair observer and commenter.
That said, I do intend to write more about my observations about contemporary Black English. But not now.
