1. Send them all back to Africa, never again to return to Europe or the Americas
2. Ensure their cultural, intellectual and economic prosperity
And a wish, not so much for black people in general, but for the black genie himself:
3. Go with the rest of his folk.
To be clear: I have no belief that blacks are naturally inferior to whites, nor do I wish harm, collectively speaking, on the black race. We are bound to wish them, and all men, the best, insofar as all men are made in the image and likeness of God. I think that, for any given black person you come across, all other things being equal, you should treat him or her with the utmost respect and consideration.
I just personally don't want to have to deal with them, or else, be inconvenienced even by the mere sight of them.
