Little Johnny and little Flo watched that American PBS series, Roots. 

'If you are a  bad boy,' said little Johnny's momma, 'then you'll be sent to America  in chains to pick cotton.' 

'If you are a bad girl,' said little Flo's momma, 'they'll send you to Australia where you will be raped by white devils.'

Every black parent told them that killing a white person ensured that the black race lived on.

'They want us dead,' said little Johny's momma, 'so if you can cut off a head of a white guy, son, you will ensure the Zulu's rule the Greater Serengeti.'

The Greater Serengeti was the rest of the earth.

Black dominance.

Until then, 'chop their fucking heads off.'
