Do you ever stop and wonder, what it is Niggers really are? I know the truth, and to you I will give it.
Thirty-six thousand years ago a race of superior alien beings came to earth. They landed on the gigantic and empty continent known today as Africa, and in their load they carried a big number of dark-skinned individuals - niggers - who they brought along as slave labour from Mercury. The reason they are black is to protect them from the strong UV-lights so close to the sun.
Niggers were harmless beings as long as they remained under strict control of their masters and were not allowed any own thoughts. If left alone in groups they quickly grew greedy and started running rampant and misbehaving. The humanoid aliens who cruised in spaceships of diamond did not like Earth, for it was populated by a race of very similar beings, Neanderthals and whatnot, so they quickly left. Of niggers however, they had a great surplus, wherefore they left them to die on Earth.
The problem is that the niggers didn't die; They instead continued to flourish in their primal ways, seeing as they were unable to evolve any form of culture. They still lived in their tribal villages and townships when the Europeans arrived and brought them along on a journey cross the globe. Only now we are supposed to treat those apparently inferior beings as equals; and if we disagree that those alien scum are equal, we are racists and nazis and must be purged. Time is right for action. We must do something about this threat, for THE BLACK PLAGUE must be defeated! Their beastial manners surely is not the way civilised man lives!
