This was a powerful update to the history that I was taught in school. Some of the things in this book were familiar but many of them were new to me. I found myself appalled at all the racists things that have occurred in the past, even by well-meaning people who would probably consider themselves to not be racist. In this way, it was an enlightening look at how members of American society perpetuate racist stereotypes in everyday life, with important implications for how we act in today's society. I look forward to reading more of Kendi's work as I become more conscious of these biases in society.
