I am. That chapter is from a book of provocative thought exercises, designed to expose people’s prejudices. And a very good job it does, too!
From the introduction to that book:
“I ought to note that the opinions expressed in this book are not necessarily my own. That is, I did write them and I didn’t copy them from anywhere else — but what I’m saying is that my chief concern in writing each chapter was to be thought-provoking, rather than to accurately portray my exact personal opinions or to convince anybody to share them.
This book is intended to interest and entertain you. Consequently, you will find some strong opinions and some strong language. I personally find this approach much more entertaining than wishy-washy don’t-want-to-offend-anyone opinions — and I hope you will too!”
You see: It’s important to see things in their proper context! :)
