I'm basing it partly on the speech he gave in Houston a few months ago, where he went on -- to a black audience -- about how "we" need to stop feeding our kids Popeye's chicken for breakfast, be better parents, etc etc. He's made less flamboyant versions of that move repeatedly, including in his 2004 Dem Convention speech. I suspect the defensive response is something like well it's true that some people do that, but I think that's at best a bullshit, Kool-Aid junkie's rationale or worse evidence of embrace of the same kind of class-driven behavioralist narrative about poverty, that nowadays often enough comes dressed up as race-conscious community "uplift."
