The demon seed line of jews comes from Lilith. 
This sounds outlandish until you really study it.

This is why the jewish lineage is matrilineal and not paternal. One third of the angels in heaven are fallen angels, demons and they live among us. Where do you think they live?

And since their bodies are hosts for the fallen angels (demons), they actually benefit from the dysgenic nature of their crossbreeding with the worst of other races. They have the most dysgenic genetics,so as to create the perfect host for a demonic entity.

 Thinka bout this: they get sickle cell anemia like niggers, they are lactose intolerant, they have ugly physical features, sloped foreheads, hooked noses, afros, beady narrow eyes, high rates of mental illness, low muscle mass, small penises, pooor physical coordination, zero athletic skill, extremely high rates of sexual perversion, incest, pedophilia, dementia, the list goes on and on. And lets not forget, they are pretty much are all atheiests. Ironically this makes them evn more susceptible to being "perfectly possessed" by demonic spirts.

The few things they are good at overcomes everything else though. They have silver tongues, they can spin circles around the average goy, telling lie after lie, and if caught they will just switch subjects, or make ad hominem attacks.They are gifted at creating lies and actually beleiving their own lies. They have intense in group preference. And lastly, despite their poor genetics, they seem to live forever, though this seems to be more tied to their penchant for human sacrifice, and eating babies. This wolrd is run by their demon god Molech and they are in control right now.
