Query: Blinded by bitterness

Anyone who has spent time in Brazil will clearly see that the author of this book is constantly either blowing all brazilian bad qualities way out of proportion, or twisting information to create some that simply don't exist. He seems to be a very bitter man blinded by his bitterness and everything he sees is inherently bad. Only people who has never been to Brazil will find this book interesting and that is because they don't realize that it is just a sequence of either inaccurate or absolutely false information. Only people with a tendency to bitterness will be able to see humor in it. If you truly want to learn about Brazil and Brazilians you shouldn't read this book.
