Setenta -
It is my understanding that major traits take many thousand years. Such as making better athletes or stronger muscles in a batch of slaves over 400 years with debateable eugenics programs in the south.
Not only this - but what counts as stronger - stronger mentally or stronger bodily in terms of survival? It seems that those who willed to survive the beatings and work may have fared better that the bodily stronger.
I think Setenta - that my tone was too flippant because I saw this as a Jimmy the Greek style statement. "Blacks have an extra muscle in thier leg."
I can see that you have studied this in depth (perhaps more in depth regionally than I have) and can see why you you said what you said. I should have taken more time.
Also, even as I typed "decimated" I thought about the roman conception and wondered if that was going to hold. It did not - and rightfully so.
The point I was trying to make is that you can't argue the means by arguing the conclusion. You can't wack someone over the head to get them to take thier medication and tell them (ethically) that is was for thier own good.
This is taken a step further when whole populations are wiped out (certain islands and costal regions of Africa - as you mentioned) and then we argue that Africa is desolate and America is so much better (after it was built on slave labor).
You assume the conclusion within the premises and the argument looks something like.
If we enslave a nation and transport them to another nation and then let that nation prosper on thier blood and sweat - the nation that we moved them to will be better off and thus the newly released slaved will be better off.
As my logic instructor said when he saw something that begged the question " No **** Sherlock."
I should have explained what I meant better above - but my experience is that people want to clear thier white guilt by making all sorts of outlandish claims.
Thanks fo your clarifications and patience.
