To put it in context though, Roger, Johnny Lee Clary has apparently shown total remorse, and is now a preacher devoted to evangelising against racism, and anything but a friend of the KKK. In that light, this particular anecdote is very much at the expense of the KKK and in praise of the man who "defeated" them.
Certainly, I think anyone has the right to question his motives and be cynical about his apparent celebrity within his 'conversion' (he was a high profile KKK spokesman beforehand - I remember him well from his appearance on Oprah some years back), but the appearance is that he is at least on a better path than the one he trod before. And that is a little heart-warming I think, even if it doesn't excuse the actions and ignorance of his past.
