Subsaharan Africans are indeed a primitive if not stupid bunch, it is not their fault that they are less evolved. White people have no real right or need to hate others for being less evolved, do you hate monkeys for being less evolved? Do you hate dogs for being less evolved?
White Americans should not complain about "niggers" since they were imported to pick cotton, if white Americans have a problem with "niggers" I suggest you take your business back to Europe. Or start a political movement for a white country in North America.
Multi-cultural/multi-racial societies don't work anywhere. Instead of complaining on the internet I suggest you do something. The US is going down the toilet anyway, the opportunity shall rise soon, be prepared.
