No I didn't think he was perfect before. And I wouldn't say that my image of him is "shattered" I still think he's and OK guy.
Which part of the book is invalidated because of what we now know?
Nothing particular. I just don't like or value stupid people. Blowing 8 million bucks is stupid, and knowing that about him makes me think less of him and his opinions in general. The book of virtues is great, but it's not just a collection of stories. It's a collection of storeis put together by Bill Bennett.
