As I've said before, the issue is not "reparations", it's "tax cuts", and Keyes has come up with an ingenious way of morphing one into the other.
While certainly controversial, it makes some sense, as a means of shifting black voters' mindset away from welfare-stateism but some people here hate Alan Keyes so much, they refuse to consider his idea seriously.
He is trying to get the attention of black voters in Chicago, and peel off enough to make the race competitive. This could work, although it's still a long shot.
It is not ingenious; it's insulting and insane. The best way to propose tax cuts is to, well, support tax cuts for *all*, not reparations. I swear, Alan Keyes could decide that partial-birth abortions were a good thing, and his supporters would still try to justify his position!
