Why don't black people like pizza at all?

I mean I know they eat it and I'm not trying to be racist but It seems like all my mexican friends, arab friends (they don't eat pepperoni though) and asian friends love pizza. We always order it when we drink and every black person that has ever been at my house always wants "chicken wings" again not trying to stereotype! or complains about how they hate pizza. I also was a delivery boy for papa johns in E St Louis of all places where there are TONS of black people and none of them ever ordered or came in. Is there such thing as a black person who orders pizza on their own free will.
