If you ever see "Jews" secular or "religious" in Israel, America or anywhere else who hate Judaism, or Israel, or support the enemies of the Jewish people these people are not Jewish at all. They are the descendents of the Erev Rav. The Erav Rav were Egyptians that left Egypt with the Jews, 3300 years ago. Moses converted these people without G-ds approval. They are/were the ones that gave the real Jews problems. The building of the golden calf was they're fault. the Zohar says that in the end of days when the Messiah will arrive to Israel the Erev Rav will wage a war with him.
