It is simply racism. All racists have ‘reasons’ why it is ok to apply different rules to different demographies. The fact that leftists do not say, ‘we are discriminating against group X, but we are discriminating FOR group X does not make a single bit of difference. Either you are racist or you are not. Affirmative action is racism, but, much like the Islamic word for ‘justice’ which actually means that all in the circumstance are subject to sharia law with Muslims being supreme, ‘affirmative action is just good ol’ fashioned racial discrimination.
I would be much much less likely to hire a lawyer, doctor or engineer who had the bar lowered for him because of his demographic and frankly, people in the groups selected for should really be furious. To accept these benefits is an admission of lesser ability.
