It is an excerpt from Tracy Thompson's book, "The New Mind of the South," published by Simon & Schuster.
I am still reading it, and it seems very interesting. She does seem to know her Lost Cause history.
With Simon & Schuster and the media coverage her book should become well known.
One interesting thing is that Thompson tells the history of the United Daughters of the Confederacy (UDC) purging professors from universities. Remember that when some neo-Confederate is complaining about something being "politically correct."
