So if you know someone who is like "taking down statues is changing history", just point out there was a movement to put a Mammy statue on the National Mall. I already knew this because of Melissa Perry-Harris' excellent book. McElya's book does a great job of showing the harm as well as the reason for the Mammy myth. This book is well worth reading.
Additionally, when certain people lost their sh*t over the change of a certain pancake syrup, this book illustrates why that change was long over due. Mrs. Butterworth, we're coming for you.
(honesty, people just use real maple syrup).
