Wright was not an aberration. Wright represents a certain way of thinking which has pretty much absorbed the black Democratic leadership. Obama gravitated to Wright's church because that kind of thing is expected of anyone who is going to make any progress in Democratic politics as a black person.

If anger and frustration are "passed on to the next generation," it's mostly because angry, frustrated people make better political cannon fodder for the Left than successful, self-reliant and self-confident people.
Whatever that little girl was really thinking, this speech shows what Michelle WANTS her to be thinking.
