Why don't the negros thank us?

We saved them from Africa, why aren't they thanking us?  The pussy euros thank us every day for saving them from Hitler and Stalin and Saddam and whatever, why don't the negros do the same?

america= oppressed people from everywhere else in the world. As for thanking white people what about slavery. Also most of the lynchings befor the civil war were white people after it became Blacks, Whites, and Asians(westcoast).
