Cliff Notes version:
Obama says the Warren court is seen as radical because it did much to advance civil rights but it really wasnt because it didnt sweep away the contraints in the constitution on redistributing the wealth. Then when asked by a caller if the best way to accomplish "reparative economics" is through the courts or the legislature he goes into a diatribe about what the most efficient means to do it is.
Reparations. He’s for it and he’s going to make sure it happens.
Was he ever asked whether he supported reparations? Not that is matters - he lies and when caught, attempts to crush anyone who calls him on it.
