That is because they don't understand history. Affirmative Action was intended as Reparations. It's obvious that white women weren't minoraties before, but only became so after 1968 when Affirmative Action was implemented. One could say that Hillary Clinton for example became one of the early beneficiaries of something that was meant for Black people. She gave thanks by propagating that Black males are "super predators".
Black people now are the least likely group to make use of something that was meant specifically for the Black community (btw, not Black immigrants).
White women benefit most from affirmative action — and are among its fiercest opponents
