I don't know if you are familiar with Sabeel, a Palestinian "liberation theology" group that is very anti-Israeli. They host tours designed to convince Westerners that Isreal is oppressing the Palis. They host conferences and meetings in the US that present Pali propaganda. They have planted deep routes in America, mainly through liberal churches, the same ones pursuing divestment policies.
Obama's "former" church is a Sabeel church. That's where he got his perspective on Israel.
I am, an official partner of several Presbyterian and Lutheran sects. The Jews killed Jesus, they'd say an unnamed religious group "allied" to the Romans were instrumental, thus they now kill palestinians. Arafat was big on palestinians being the modern victims of the perfidious Jews. Since I've seen you on many of my threads I know you know this, but some might be surprised that amongst the friends of Sabeel and Rev. Ateek is a certain Church on the south side of Chicago which formally embraces black liberation theology. Can't remember the ministers name, maybe Rev. Wright. Married a President I'm told.
Funny, you could have read about this stuff since Obama's Senate campaign on FR, but not in the media.
And of course that's where he got his opinion of Israel, and IMO Jews. Along with Columbia, and some of his non Christian pals
