Even if nobody would canonize King for his personal life as a whole, it’s worth note that he did bring “I Have A Dream” to the fore. So what if it was borrowed (which in fact it was, word for word, from a white preacher decades before). The important thing in the context is that it was asserted.
Let’s not split hairs or indulge in self righteous gotchas over King. Let’s honor what he was most known for and then keep going.
No thanks, King defending riots:
"I think America must see that riots do not develop out of thin air. Certain conditions continue to exist in our society which must be condemned as vigorously as we condemn riots. But in the final analysis, a riot is the language of the unheard. And what is it that America has failed to hear? ........
.....And as long as America postpones justice, we stand in the position of having these recurrences of violence and riots over and over again. Social justice and progress are the absolute guarantors of riot prevention."
