Ogbar, J. O. G. (2007). Hip-hop revolution: The culture and politics of rap. University Press of Kansas.

Reflect on the arguments presented in Chapter 4 of Ogbar's book, "Rebels with a Cause: Gangstas, Militants, Media, and the Contest for Hip-Hop," where he addresses the criticism of hip-hop as a root cause of various social issues.

Considering the statistics cited by Ogbar—such as the increase in graduate degrees, the decline in teen pregnancies over the past two decades, and the heightened political awareness among youth—do you believe that hip-hop is being unjustly criticized for its impact on society? Additionally, speculate on whether these positive trends might be even more pronounced if hip-hop music were subject to stricter censorship. What implications might such censorship have on artistic expression and cultural dialogue?
