I'm not making that argument, far from it. The fact that there are many black people in this country that refuse to be victims (i.e. liberals), as well as black people in every other 1st world country that do just fine puts the obvious lie to that notion. I was merely pointing out the logical consequence of the statement "you can't have captialism without racism" infers that black people are genetically inferior.
As for even starting point, that is baloney. Immigrants come to this country with absolutely nothing, often having been effective slaves themselves in their home countries and become highly prosperous. You can't blame a 75% illegitimacy rate on the fact that your great great great great grandfather was a slave.
