It has seemed very enlightening to me. I have seen reflected in the explanations examples taken from the news about the behavior of "the right", both domestic and foreign. What I have not found are examples of what he calls "the left" or "the progressives".
Either I don't know how to see them, or they don't exist in my imagination.
What he describes as progressive, in my understanding, is as idealistic as it is non-existent.
In any case, I recommend the book. It is short and easy to read but it leaves you with concepts that make you reflect. It makes you think about the different political positions and how they are presented and understood. It also makes you question your own assumptions and beliefs about what is right and wrong in the political sphere. Overall, it is a thought-provoking read that I would recommend to anyone interested in politics or social issues.
