I think that I am with ER on this. While there may be a great deal of potential in hip-hop culture (energy, passion, drive, creativity, and at times profundity), I also see very little in the way of sustained critical engagement with substantive issues in a reflective and reflexive manner.
Culture and art are extremely powerful tools in the pursuit of justice and the end of subjugation, domination, and exploitation, but they are not the only ones. More and deeper analysis is necessary. For example, the comment "we are pulling ourselves up by the bootstraps and bringing capital America to its knees" shows an incredible amount of economic and political naivetÃ©.
I applaud the efforts of individuals such as Cornel West, Michael Eric Dyson, the critical analysis of the scholars such as Trica Rose. Yet, hip-hop is into its third decade, and I am not sure if the future will see much more coming to fruition than we have seen in the past.
