You didn't see the message he was responding to?
"Farewell Crackas it was nice to share the planet with you."
That doesn't sound particularly concerned. Did you not follow Farrakhan's reasoning? If the white people completely mix in, there will be no more white people. Sounds right to me. It also sounds like ethnic cleansing.
Now it might not mean anything to you, if your grand children don't look like your grand parents, but to other people it does. You can call that ignorant if you want. I personally don't want to be dissimilar to my own grand kids.
You are free to do whatever you wish, but what Farrakhan says is true, and it isn't wrong for white folk to be concerned about it.
What we SHOULD be doing, instead of playing politics.
