A friend here in Arizona has O'Reilly's book. After dinner at their home one evening I read a few chapters and was pleasantly surprised. They offered to lend it to me. Will take them up on the offer after reading all of the books by Ace Atkins (former Auburn football player turned NYT best-selling novelist).

You can't judge a book by the cover or the title. One of the best books I ever picked up has this title:
What Lincoln Believed: The Values and Convictions of America’s Greatest President, by Michael Lind. Obviously the author admires Lincoln, but his book makes most Lincoln admirers squirm. On social occasions with our Yankee friends, my wife admonishes me not to mention the book or anything from it. It has a way of souring their milk.

As one reviewer noted, "Cromwell famously asked for his portrait to be painted 'warts and all.' Lind has given us a picture of Lincoln that can fairly be characterized as almost nothing but warts."

As long as it's factual, well written and covers all points, pro and con, a book shouldn't be rejected based on title (or author).

Knowing that my pastor follows news media personalities, I asked him for an opinion on GB. Response: "He a useful idiot. Sometimes useful, mostly idiot."
