I just bought this book -- "The End of Faith" by Sam Harris -- and found myself agreeing with almost every paragraph. It is about religion as a bad thing -- "religion, terror, and the future of reason" -- and would probably be more for the atheists than anyone still involved in a religion but it does make some good points. It is about all religions, not JW but it includes all religions in its sights.
I'd have to practically re-write the entire book to give examples of parts I liked, but I'll copy this one as a taste:
"Tell a devout Christian that his wife is cheating on him or that frozen yogurt can make a man invisible, and he is likely to require as much evidence as anyone else, and to be persuaded only to the extent that you give it. Tell him that the book he keeps by his bed was written by an invisible deity who will punish him with fire for eternity if he fails to accept its every incredible claim about the universe, and he seems to require no evidence whatsoever." The End of Faith, pg. 19
That's a good start to give some idea of the tone of this book. I haven't finished reading it but see no resaon to think the rest will be any different. I'll have to use that yogurt = invisible man one if I get the chance.
There are also a couple of interesting thoughts about how a 14th Century scholar would stack up intellectually with a modern child in grade school and some comparisons / contrasts of ancient biblical truths or realities and how they would be perceived today. Fascinating.
So far it is a really good read. But maybe that's just me ...
