The sad thing about this thread is that no one has yet made the simple observation that the American way of life is STILL built on the backs of slaves.
Slavery has been disassociated (somewhat) from race, hidden offshore, and in undocumented migrant communities, but it absolutely still exists and is fundamental to the American way of life.
So,the real question is: how can all of you people who claim to believe in equal rights turn a blind eye to the continuing forms of slavery that--by the way--brought you the very shoes on your feet, the meal on your table, the gas for your fine automobile, and the wide variety of technological gizmos that you bought for yourself this Christmas in order to distract yourself from the consequences of your overwhelmingly materialistic and violent way of life.
