Israel Shahak I have discussed before. He was a man who spoke out against Zionism and the goals of the IsrAmerilis project- the foundation of Israel.
Here's some examples of fact as opposed to this persons fiction-
1)The Talmud, which consists of rabbinical interpretations of the law, treats Christ and Christians with contempt. Unlike the Koran, which regards Christ as a great prophet, the Talmud contains "very offensive precepts and statements directed specifically against Christianity.
2)The Talmud treats non-Jews as sub human and directs Jews to discriminate against them. For example, the concept of adultery "does not apply to intercourse between a Jewish man and a gentile woman; rather, the Talmud equates such intercourse to the sin of bestiality."
3)Shahak disputes whether Judaism is in fact monotheistic: "In many if not most of the books of the Old Testament, the existence and powers of 'other Gods' are clearly acknowledged, but Yahweh (Jehovah) is the most powerful of his rivals, and forbids his people to worship them."
4)The Old Testament does not have the same place in Judaism as the New Testament has for Christianity. Most biblical verses are reinterpreted by the Talmud in a sense that is distinct and quite contrary to their literal meaning. For example, the famous verse 'thy shall love thy fellow as thyself' (Leviticus 19:18) is understood as an injunction to love one's fellow Jew not any fellow man.
The discussion goes on, but what it implies is that the Hebrews are really the cause of the conflict that dates back 5000 years, and that it would be only natural to believe that there would be a force to counter this obvious bigotry and hatred.
It appears the Hebrews and their descendents have brought this karma of hatred upon themselves. It also appears that their god is not a true god after all, but one manufactured to justify this racist bigotry and hatred they purport to others.
According to Shahak, classical Judaism is not so much a religion as an tyrannical system of social control administered by rabbis. Ordinary Jews were forced to obey a labyrinth of capricious laws on pain of fines, beatings or even murder, administered by the non-Jewish aristocracy that would get a share of the fines.
This article brings lots to the table for such a short article, but says a lot that this man/woman should be informed about.
