Query: Garbage

This is just another so-called "historian" engaging in the useless, masturbatory exercise of condemning the great figures of the past on the basis of what would be considered acceptable (i.e. PC) behavior today. When James McPherson - a real Civil War historian (and hardly a conservative) - says that this author got more wrong than he got right, it really tells you what this book is worth. It's not worth the paper it's printed on.
