The apartheid regime was a crime against humanity; as illogical as it was cruel. It is tempting, therefore, the simplify the subject by declaring that all who opposed it were wholly and unswervingly good.

The real tragedy is that too many in the West can’t bring themselves to see what the great man himself has said all along; that he’s just as flawed as the rest of us, and should not be put on a pedestal.
