He was from there, SOME Jews have significant origins to Judea, however they will not have white skin, as that is simply not genetically possible, Jesus Christ had likely, brown skin, black hair, most Jews in Israel today are settlers with far less connection to the land than Palestinians
Yes Jew came from Judea, however most European Jews do not have significant middle eastern admixture, and often stem from converts in the Caucasus and Balkans, (Kazars) Palestinians are the native people, this would be no different than saying Yakut people come from china, while they have some Chinese roots, they as a people mixed in with the local populations, much like how Ashkenazi Jews formed by fully cementing in with European populations, thus making them Eastern European (often around 70%
Not denying there are significant Jewish populations with near full middle eastern admixture, these are those who moved back into Judea once the Roman Empire split, as you know long before the modern settler state of Israel, Jews were still consistently living in the levant, even in ottoman Palestine Jerusalem had a significant Jewish population (who were freely allowed to practice btw)
Throughout most of Eastern European history yes, primarily Spain and Western Europe and Balkans would lead in explosions, in the Muslim world they could practice freely, they just had to pay jizya, however paying jizya means that Jews wouldn’t be conscripted, while Muslims had to pay zakat (higher than jizya) and be conscripted
It’s not eugenic, eugenic is when you are attempting to eliminate certain genes or certain groups of people, not pointing out basic facts of ancestry, and while racial tests have only been around for 150 years, most ethnic groups have completed ethnogenesis 5000 years ago, this is not saying anything about superiority, it is just simple facts
