He still used MLK as an icon of good character, despite the fact that MLK was a womanizer and a communist. I'd say there's some edoocashun missing there; other than that, a decent job of ruining his chances of a repeat performance and good write-up in the college paper.
Being a womanizer is irrelevant. Plenty of great men have been. MLK was obviously fearless which I think is a defining characteristic of all great character. I think MLK made use of communists and that it was understandable. You're going to be a very lonely voice claiming he was not which is fine of course but just will never make a difference.
Ben Franklin was a womanizer and Churchill was a drunk. I'd say they showed character when it was needed.
MLK was not a communist, btw.
He didn't use MLK as an icon of anything; he repeated a quote of MLK's as an insightful description of character.
It was the power of the idea, not the personal habits of the speaker, which was worthy of consideration.
I think you missed the whole point. Look at Chesterton's quote.
