I'll say first that I downloaded the author's guitar book and I plan on studying it and learning to be a better musician than I am now.
As to this one, it opens with the line: "This mini-book is for smart people who want to the ability to not only tolerate, but discuss deeply with those who hold radically different views." I do hope that is true and that many people read this because in so many cases the "left-wingers" with whom I have tried to have discussions have proven to be rude and intolerant of any opinion that differs from their own. It's possible I've just run into the "wrong" side of the party but my experiences in the last 20 or more years have not been pleasant.
The author further states: "Conservatives are, however, often characterized as anti-evolution , anti-global warming , anti-abortion , anti-social security , anti-universal health care , anti-immigrant , and just plain bad people ." Again it is a shame this attitude exists since I am none of those things. Granted if you lump everyone into a single pot and use clowns like Shawn Hannity as your role model then you will come away with a bad opinion.
What I'm trying to say is that you can find intolerant a-holes on both sides and when you encounter those people the best advice is to walk away and leave them to their delusions since you will never change their minds anyway.
The book is good and it makes some fine points. I only hope its readers will keep in mind that the door swings both ways and that "arguments" get you nowhere, while "polite dialogues" although they may not convince will at least earn you a bit of grudging respect.
