I highly recommend Reich's book _Who We Are and How We Got Here_.
I highly recommend that people who read the book also read criticism addressing the authors understanding of race and genetics in said book, such as https://www.buzzfeednews.com/article/bfopinion/race-genetics... quote: ‘Reich’s understanding of "race" … is seriously flawed.’
I have read the book in its entirety and thought the crude notion of "race" attributed to Reich in that letter was a strawman. Of course he doesn't subscribe to scientific-racist notions from a century ago! Have you read the book?
