Two thoughts for now:
1. While most Liberal Jews support people and policies that are a disaster for the Jewish people, 17 Jews doesn't seem like a large enough sample size to get an accurate picture on the overall opinions of Jews.
2. At the Times Square Rally, the only Jews with very few exceptions that attended ( around 12,000 people attended overall ) that are in favor of the Iranian Nuclear Agreement were the hideous N.K. Jews. Those are the ones that support enemies of Israel and sent a representative to an Iranian Holocaust Denial Conference. They seem to be at practically every Pro-Israel type of rally, voicing their opinions against Israel. There were confrontations between them and some in the crowd at the Wednesday Rally.
