Re your sig, I do wonder what MLK would have thought of Israel these days.
(and yes, I know this is veering off topic)
The unfortunate thing about MLK is how much he, a socialist, has had his words usurped by people who would have hated him when he was alive. That includes so-called "libertarians" who love authoritarian governments and militaries.
I doubt very much he would have approved of the current apartheid situation. Certainly, those words were spoken before Israel decided, intentionally, to slaughter Lebanese civilians in the 1982 Lebanese War (marking schools, churches, etc. as targets) and before they had transitioned into their system of settling stolen land from the Six Day War. Who knows, though, we can only speculate.
I also love their insistence that the only problem with Israel is the actions of the Netanyahu regime, as if they've never heard of Begin. Then again, given the source, that might not be far from the truth.
