It’s just a book. Without your mind to give it meaning, it has no meaning. If you’re so easily offended because you’re sensitive like a mimosa, it’s capitalism, don’t buy the book.

You had better concentrate on the examples if you want to learn something; don’t be such sensitive daisies.

And it’s the author’s book, he can and may put any kind of examples he wants; when you write your own book, you get to do the same thing.
