Jewish heritage is pretty dark.
Read the Talmud, and read about the passages in there about what a Jew's attitude towards non-Jews should be:

My theory is that due to Jewish religious beliefs all of the honorable Jews with low in-group loyalty were killed out over time. With increased inbreeding and selective reproduction, Jews eventually started to carry many genetic procilivities towards extreme in-group loyalty and disdain and xenophobia for out-groups. In other words, they had the exact opposite stimulus for development that white people did, however, they developed alongside white people. So, what you have are a people designed for infiltration and cruelty to the outgroup, with intelligence equal to white people with a higher general intelligence especially socially and verbally (as the success of Jews was guided by their trade and verbal skills.)
Some of the largest crime syndicates in the world have been Jewish. I have no doubt that many crime-lords and flunkies have converted extensively to Judaism, further bringing those sorts of genes into their genepool. All in all, I feel rather sorry for the small pockets of unaffected Jews unlike their brethern. I don't think that they have any hope whatsoever in chasing the course of the boat called world Jewry. Of course, their best hope is to convert away from that identity ASAP. After I started researching my mother's Jewish heritage, that's what I did. I don't want to have anything to do with such a disrespectful,selfish, and bigoted people. Judaism and the Jewish people in general since the Pharisees has been a train-wreck waiting to happen.
