I always refer to this book as “the book that radicalized me.”
Intellectually, I knew that the history we were taught in school was sanitized and, in the words of the old maxim, “told by the winners” — but knowing that, and reading it in black and white, were two different things.
This book is one of the contributing factors to why, despite the conventional wisdom that you grow more conservative as you get older, the exact opposite has happened with me.
