On the anniversary of his death, pundits of all sides talk about Martin Luther King's legacy. That's fine, but then they start saying what he'd be doing if he were alive today. (There's even a book out on the subject.)
It's a pointless exercise, and not just because we don't know for sure what he'd think. King was a man, not a god. As great as he was, not everything he believed was right. And if he were still around today, I suppose he'd be making pronouncements on the passing scene, perhaps leading movements, but while we might respect him, it wouldn't mean we have to agree with him. In fact, I'd guess most of the people today who claim him for their own would be disappointed in one way or another, and wouldn't be afraid to make their differences known.
