A Challenge For All Liberals
Format: Paperback
I thought the book was well-written, impeccably sourced, wide-ranging, and with a thesis that can't help but make you think. Well worth your time.

The history is unpleasant and therefore worth knowing.
It's a wonderfully enlightening history of how European explorers visited, settled in, conquered, and exploited other continents with unparalleled cruelty in the name of power, greed, and their "loving" religion that brought them misery, exploitation and, all too often, abject slavery.

Wonderful History Lessons
I ordered this book to use for a college paper I was writing and found it fascinating. I enjoyed the content and learned much from it.
The history is written in a manner that for those people that either don't read much or don't like to read (yes, there are a few people out there), it will draw you in and make you question the history lessons we suffered through in high school.
