Race exists, no one sane has suggested it doesn't. Affirmative Action is a remedy for institutional racism. [are you brain dead?]
How is "institutional racism" responsible for the fact that blacks tend to score poorly on all the mental aptitude tests however they are designed?
How is "institutional racism" responsible for the fact that blacks tend to perform poorly in public schools, even when they are well financed?
How is "institutional racism" responsible for the fact that blacks have a rate of violent crime that is nearly eight time the white rate?
How is "institutional racism" responsible for the fact that blacks have an illegitimacy rate that is three times the white rate?
It is institutional because the libtards run everything, and they treat blacks with condescending policies that fail to challenge blacks. BTW your stats are only true of subcategories of blacks, not all categories of blacks, Ethiopian immigrants, for example do not have these problems, nor do most Jamaican immigrants.
Low income would be a better indicator of these problems you describe than race is. Impoverished white wards of the state do as poorly as impoverished black wards of the state. Degreed professional blacks do far better than lower class whites in the categories you mention.
Again, race is not the critical indicator.
