It's ironic that left wing Jews seem to be so much in favor of illegal immigration and civil rights for blacks, etc. when all it does it come back to bite them and unfortunately any other Jews, even the right wing ones.
The Latino churches tend to be Catholic and while we have many good members at JTF here who are Catholic and not anti-Semitic at all, it's also worth noting that there have been leaders within the RCC in recent history who have been more pro-Fakestinian than pro-Israel and considered Muslims closer friends than Jews. I still remember that picture of Pope John Paul kissing the Qu'ran. That was just so wrong.... and I think many of the Latinos in third world countries might have been badly influenced by such things and may not have been brought up to respect Jews, so when they come here they carry the same attitudes with them.
Black churches are sometimes influenced heavily by Islam, as Obama's so-called church demonstrated. I've noticed a strong tendency even among non-Muslim blacks to have a sort of respect for Islam and to name their children Muslim names (Like Ayeesha for girls or Omar for boys). I think that the black community also resents the fact they needed so much help from Jews to acheive all the handouts they've gotten rather than being grateful at all for that help.
