Not at all. You mentioned a book I don't have, but I don't believe for a second that it supports the notion that Mrs.King knew, or claimed to know,  MLK to be "unrepentant." She couldn't know that any more than you can. 

You described Dr. King as "unrepentant." It's a hypocritical assertion you cannot support because you cannot and do not know his heart. You claim to know what only God knows: textbook blasphemy.

A cowardly retreat is one way for you to unwind from the predicament you put yourself in.  Another would be to acknowledge your mistake.

A rhetorical question (because I know you can't answer it): How do you reconcile your petty hypocrisy with the putrid pablum that permeates so many of your other posts?

A final question which I assume you won't answer, because you've been dodging it most of the day:
You described MLK as unrepentant: Do you know his heart at the time of his death?
