I'm a white Southern male and strongly support affirmative action for black people.
They are treated poorly to this day by authorities and still feel affects of slavery and Jim Crow. How many black people's great grandfathers went to Harvard or Yale to establish legacies and tradition?
They had to form their own colleges and universities through the black church.
George W. Bush couldn't get into the UT --Austin MBA program because his grades sucked but he got into Harvard Business School through family connections/legacies.
Affirmative action is in place to balance out such inherent unfairness in the world.
