"Who the fuck are you even talking about? Palestinians, Black Africans or Canaanites? Gergemites maybe? Pick one. See, I'm thinking you're the dense one."
Well we were talking about the curse of ham, right? Isn't his son Canaan the one who gets the curse put on him, and put into a life of servitude? Also isn't this particular set really symbolic of the various nations/people that inhabited the world? The bible includes many passages that are merely political passages-- such as the referencing to other religous figures as Demons, like ba'al, a horribly apt figure-- in the same sense this statement offers an interpreted view of history. Obviously it was written in a similar style as most early, mythological/religous documents.
Also you might find that alot of the stories about genealogy in the bible are symbolically(or not, i don't know) referring to how the various civilizations of the world came to be, and the inter-relations of them, often outlining actual historical events. That's a pretty basic format as far as religion goes.
Also Kush is the name of Ham's oldest son, and similarly, Kush is also a nation.
