How would it help to not acknowledge that black people are politically and economically diverse? Ignoring the needs of middle class blacks for poorer blacks (and vice versa) doesn't really help "black" people. The two groups generally have different agendas, goals, experiences etc. Someone who is black living in the hood, who is chronically unemployed, unskilled, with a prison record and with children isn't going to have too much in common with someone who is middle class, college educated, law abiding, married and employed (and that' s not intended to shyt on anyone poor--I'm just outlining polar opposites) just because the two of them are black. But that's not my point in its entirety...the other end of the problem is that he draws cross comparisons to other groups who are very new, much smaller and much more homogeneous.SO in otherwords, you can't look at Gays, and Asians and then say (collectively) why can't blacks do that too? Well the reason is obvious...blacks as a "collective" really aren't a "collective" group at all. They're far too diverse politically, economically and regionally.
How are they suppose to get on the same page and put together the same agenda just because they are both "black" ? For who, for what?
As far as the foundation of his arguments...well IMO they are generally based on a false narrative. If you build your argument on that--then everything after that is basically false in principle.
