Just like the Jews in Germany when the Nazis took over. Among German Jews there were optimists and pessimists.
The pessimists wound up in America. The optimists wound up in Auschwitz.
Even in Israel where being Islamosavvy is a key to survival, there is a Left faction that really believes peace is possible with those who would destroy them.
SPLC is an ally of Islam. Its founders Morris Deas & Chaim Potok are Jewish. The Orthodox rabbis get it, however.
They mostly vote Republican, too.
