Is the Willie Lynch Speech a Fake?

Lately, I have been running across references to the Willie Lynch letter or finding it frequently on blogs. Willie Lynch was supposedly a successful slave owner/trader who went to the West Indies to lecture slave owners on slave sociology and how to owners could keep their slaves in check. After reading some arguments online, I have made my conclusion that documentation of that 'speech' may have been fabricated. I don't want to get into a debate as to whether it is true or not, but what about the content of the letter? Are we living out the lives with the same behavior "Willie Lynch" purported would keep us down and under control. If you have not read it, here is the link. Whether it is authentic or not, read it once. Does it matter whether it is real or fake? Can we learn something from it? The Willie Lynch Letter and The Making of a Slave
