I do think he deserves to be dissed,talking about how The Roots don't have an identity,and they contradicted themselves,Nas also said they are "Fake rappers". I didn't understand the whole response about the dreads,but he did diss the Roots and I think it's time Thought and the Roots showed the non-believers the lyrical skills they possess.
