When I'm at a loss for words...

...I can always turn to Dennis Prager. In this case, the US Presbyterian church decided to side with Arafat, Hitler and the Saudi's.
That this is an especially vile thing to do for a Christian is what Prager so efficiently pinpoints.
Presbyterian church defames Christianity

It takes a particularly virulent strain of moral idiocy and meanness to single out Israel, not Arafat's Palestinian Authority, or terror-supporting, death-fatwa-issuing Iran, or women-subjugating Saudi Arabia, for condemnation and economic ruin. One of the most decent societies, one of the most liberal democracies in the world, is fighting for its life against Islamic fascists who praise the Holocaust and publicly call for the annihilation of Israel -- and the Presbyterian Church calls for strangling Israel!

Apartheid state? This Goebbels-like Big Lie, concocted by the world's anti-Israel and anti-American Left and by those who want Israel destroyed, is now an official doctrine of the Presbyterian Church. Israel is a nation whose population is one-quarter non-Jewish Arab, with the same rights, including voting and its own political parties, as Jewish citizens; a nation whose second official language is Arabic, the language of those who wish to annihilate the Jewish country; a nation that occupies a tiny sliver of land known as the West Bank only because Jordan, overwhelmingly composed of Palestinians, invaded Israel in 1967 in order to destroy it and thereby lost its ownership of the West Bank.

With all due respect to those Christians who do not blame the Jews for the murder of Jezus Christ (any longer), but that stigma will take another 2000 years to disappear. And the US Presbyterian church's attitude in this matter is a sure sign some Christians have a long way to go yet.
