I have answered the most difficult question about Jews. What is the source of anti-Semitism? The answer is the presence of an hereditary elite class. Hereditary elite classes use anti-Semitism to distract attention from their own overlord position. Jews are the perfect scapegoat. Successful and tiny in numbers.
The second most difficult question about Jews is "Why have Jews been voting so overwhelmingly Democratic for more than 70 years in America?" This I can answer.
The question arises because Nixon and Reagan were friends of Israel and George W. Bush was the greatest friend of Israel and the Jews in 2000 years, the greatest friend since King Cyrus the Persian.
On the other-hand, Jimmy Carter openly hates Jews and Bill Clinton, intimate friend of Adolph Arafat, went to Jerusalem at the peak of Palestinian Jew slaughter, called Intifada II, and told Israelis to be patient.
Answer to the Jew voting question: Jews for more than a thousand years in Europe have been defenseless rabbits slaughtered at the whim of their neighbors. The only possible survival response has been cowardice and willingness to pay ransom. I repeat the word 'cowardice'. One thousand years of cowardice.
An example of a stereotypical Jew coward is Woody Allen. A defenseless, ball-less, pathetic, schlemiel (Yiddish for loser). Woody Allen cowardice comes with stooped shoulders, a step-'n-fetch-it walk, and a 'laugh at poor me', demeanor.
Jews have been cowards and most American Jews remain cowards, like Woody Allen. The overwhelming majority vote for Democrats, the cowardly party that deserted the South Vietnamese after Nixon, the Republican, had brought victory in the Vietnam war. The same Democrats who tried to do the same thing to the Iraqi people, lose the war, after President Bush had liberated them.
Of course, the cowardly Jews are the same people who settled Israel from 1850 to 1960. Only persistent humiliation, bombing by their Arab neighbors, ceaseless murder by surrounding Arab countries for a century, unending war against Israel by vast Arab populations, boycotts, Arab hatred and vituperation.....only this persistent abuse has turned the cowardly Jews in Israel into a minority. The remaining cowardly Jews in Israel are protected by the brave Israelis, all of whom have served in the Israeli Army, and who have left 1,000 years of cowardice behind.
Most American Jews have no idea what Israeli's think about American Jewish cowardice. It is much like native Africans think about American blacks (their view: 'most American blacks still act and think like slaves').
