Ignorance? The difference between 0.6 human per slave and 0.667 of a human per slave is insignificant. The fact that I know the calculation makes me less ignorant than 80% of American voters. You are just dishing out the krapp today, aren't you Motley? Did you lose big on the Kentucky Derby? My sympathies, but also my advice - don't bet on horses if you don't have an inside position.

In no way does your quibbling detract from the soundness of my argument.
