This understanding that we needed to repent and reform was not confined to any particular religion: We Americans of all faiths, or no faith, used to proclaim days of repentance as a nation, especially in times of trauma. During the observance of Yom Kippur, our Jewish brothers and sisters remind us of the high duty of admitting, “I am a sinner.”

If you wear a tallit and tefillin, and blow shofar and keep kosher, but use your Judaism to undermine the right of the seven million Jews who live in Israel to choose their own destiny: Come back. In attacking your own people, you have gone further than those who renounce all traditional observance.
