Let me hammer a another nail into your proverbial coffin since you obviously are so blinded by your "poor me, pity me!" routine that you can not understand that difference between stating that all blacks should be forced to go back to Africa (which is a racist, nazist view point), and informing some one that if they do not want to have modern conveniences that they can live in a wilderness area some where.
I don't care if you find your wilderness in the Siberian Steppes, the Patagonia region of Brazil, Northern Canada, or South East Asia, the reason why Africa comes to mind is because I think you'd fit right in with all the other crazies that inhabit everywhere East of the Nile and West of the Caspian (Jews, Muslims and Extremist Christian Sects, not to mention the typical Genocidal Rants featured by people in Iran.)
As far as how it's possible for the statement to be racist, I didn't even know what your skin color was, nor do I give a damn. If you want to live in a natural state with out modern convenience, or think it would be better then there is no reason why you need to drag any one else except those that want to join you of their own free will with you.
Get off your high horse, I believe you left a metal pipe wrapped in rebar on it that you sat down on.
