If you read the Bible, you'll see that the cacodemon (evil spirit/god) Yahweh and his cult are absolute evil entities. That's one of the reason why the Hebrews keep revolting over and over again against him. They can't stand forever his Stalinistic levels of oppression. His bloodlust is amazing, even for the standards of Antiquity. Just look at this:
1 Samuel 15:3: "Now go and attack the Amalekites and completely destroy everything that belongs to them. Do not spare them; put to death men and women, children and infants, cattle and sheep, camels and donkeys."
The Yehuborim king commits the whole genocide, of innocent men, women, and children, but spares one group: captured cattle. God is furious, he can't stand even that.
1 Samuel 15:22-23: "But Samuel replied: 'Does the LORD delight in burnt offerings and sacrifices as much as in obeying the voice of the LORD? To obey is better than sacrifice, and to heed is better than the fat of rams. For rebellion is as the sin of divination, and arrogance is as wickedness and idolatry. Because you have rejected the word of the LORD, he has rejected you as king.'"
But the Yehuborim of today are not the same of Biblical Hebrews. Those Hebrews already had a horrible reputation in Antiquity for their fanaticism, misanthropy and anti-social, cult-like behavior. After the Yehuborim were exiled (70 AD), they dispersed among various Gentile populations, but isolated themselves, for 2,000 years! The Yehuborim that were reasonable, social, etc. married the local Gentile population and were absorbed in the general population, becoming extinct. There is a huge pressure for Yehuborim not to integrate, not to assimilate and to plot against Gentiles, in a self-segregated neurotic urban environment (the ghetto) which discourages birth, a population sink. There has been a huge gene pressure for selecting ethnocentric, hive mind intelligence, low empathy (empathy is not being benevolent, but being able or willing to imagine yourself among an outgroup or in the perspective of the "other") during almost 2,000 years. These populations would simply not exist if they left this religion or converted to Christianity (think about of the Amish: only their religion keeps their numbers growing). Yehuborim are extremely dangerous, and sometimes in very subtle ways. They are the group of people with the worst reputation in times of peace in the whole history of humankind. Being near them is living in a minefield.
