it's a shame this kind of [book] passes for "informed discourse" in today's society, it almost makes one feel sorry for the republicans and conservatives who claim this book as some kind of model of good writing. clearly, there are too many errors, invectives masquerading as 'facts,' mean-spirited personal attacks, and plain old nonsense for any intelligent person to bother in detail. But for conservatives, I'd have to say don't waste your time with this, because in a few years when no one listens to her nonsense anymore, you'll be embarrassed you read this instead of say, The Fountainhead. Utter silliness.
