Maybe my resolve will eventually weaken, but right now I'm thinking, "Nah. I am just not going to play this game."
I am not again going to go over and over and over with somebody what's morally reprehensible about enslaving people, even if in the end it does make them "stronger."
If it by some it chance does, the credit for this greater strength goes to the enslaved peoples, not their enslavers, and that includes my very own white American ancestors. I don't know that any of them owned slaves (I expect all of them were too dang poor), but I know for a fact that at least one or two of them were members of the Ku Klux Klan, and BTW, the Klan didn't make the objects of its attentions "stronger" either.
Either Spacebrotha is having us on, or he and I just have...how to put this?...wildly different views of history. And reality, for that matter.
