Ethiopian Jews converted to Judicism in the past, but they are not descended from Old Testament Israelite's the way Ashkenazi Jews, Sephardi Jews, and Mizrahi Jews are.
Wait, now... So what you are arguing is that black people who call themselves Jews "converted", but white people from Europe who call themselves Jews were really and truly the descendents of the Judeans? (Even though White skin in that region would be an absolute liability!)
This is almost as crazy as the Mormon belief that Native Americans descended from the lost tribes and used to be white until God cursed them with dark skin.
The Ashkenazim are whiter than I am... because I'm 1/8th Cherokee Indian. (The rest is German, Irish, English and Dutch, but probably more German than anything else.)
Two thousand years of pogroms, genocide, persecution, discrimination, the Holocaust.
Okay, serious answer time.
All that stuff was bad. It doesn't justify what the Zionists are doing to the Palestinians.
So let's look at the roots of what caused European anti-Jewish sentiment.
1) "They Killed Jesus". Frankly, I don't think Jesus ever existed as a real person, but if you take the Bible at face value, they totally instigated his death. Pontius Pilate didn't want to execute Jesus, actually went out of his way to try to spare him before giving in to the mob. (This probably has to do more with the Romans approving gospels that held Rome blameless after they made Jesus the Official God of Rome.)
2) "Money, get back, it's alright Jack, get your hands off my stack" - during the middle ages, Usury was considered a sin. So good decent Christians couldn't loan money at interest. But this didn't apply to Jews, so they could. This turned the Jews into the money lenders of Europe. And yes, this caused resentment. When a king wanted to get out of his debts, what better way than to rile up anti-Jewish sentiment. (The same thing happened to the Knight's Templar, who were also in the money changing business.)
3) Backing the wrong horse! - In Spain, the Spanish Inquisition singled out the Jews because the Jews had helped the Arab rulers run the place until they were driven out by Ferdinand and Isabella. In Germany, Jews were instrumental in the revolution that overthrew Wilhelm II, which lead to a decade and a half of misery for the German people. I put more of the blame on the Allies for insisting on vindictive terms after WWI, but any port in a storm.
4) being an isolated group, they make a handy scapegoat. - Because they lived in isolated communities with their own customs, they were always viewed with suspicion. When the Black Plague broke out 1347, people claimed the Jews were poisoning the wells. (They also went around killing Cats because cats were associated with the devil, but ironically, the cats were killing the rats which carried the fleas that spread the plague.) When the Tsarist government published the "Protocols of the Elders of Zion", which was absolute nonsense, there was no counter narrative against it at the time. (And it's still used by anti-Semites who think that it's absolutely real.
What is not a factor is, "They were smarter than the rest of us." That's just the kinds of attitudes that cause the resentments listed above.
In Harvard there used to be quotas to keep Jews out because they performed so well.
Naw, they had quotas to keep them out for the same reason they excluded Germans, Irish, Catholics, Italians, and other groups of Europeans not considered WASP (White-Anglo-Saxon Protestant) enough. That's why the whole argument of "We can't have quotas because of merit, but we can have legacy admissions" is so laughable.
Hollywood was created by Jews because American corporations did not hire Jews.
No, Hollywood was created because the initial film production companies all had to pay royalties to the Edison Corporation to make film, and they didn't want to. So it was less about "not hiring Jews" and more about "How can we cheat Tommy Edison?" (Of course, Edison was a jerk, so this is one guy I don't feel bad got cheated.)

Hollywood was an ideal place to produce movies since filmmakers couldn’t be sued there for infringing on motion picture film patents held by Thomas Edison and his Motion Picture Patents Company. It also had warm, predictably sunny weather and diverse terrain perfect for movie backdrops.
