Really? All Arab chrstians, in Israel, in Egypt, in Iraq, in Syria . . . ? You really think that All Arab chrstians are the descendants of the original Jewish chrstians? Without exception? Of course, you're also implying that Jews who still practice Judaism are illegitimate, but that's probably what you believe.
The fate of the original Jewish chrstians, though not well know, is nevertheless known to history. They were treated like dirt by non-Jewish chrstians, their bishops replaced by Greek bishops, and eventually died out completely. There is no traditional Jewish-chrstian community anywhere in the world, nor has there been for centuries and centuries.
Furthermore, when Jews were barred from Jerusalem by Hadrian (rot his bones!) this included Jewish chrstians. And even when chrstianity was legalized and non-Jewish chrstians took over 'Eretz Yisra'el no Jew (including Jewish chrstians) were allowed back in.
But anyway, many eastern Christians think American Protestants have them marked for death since American policies since the cold war ended have been a horror show for eastern Christians.
If Middle Eastern chrstians had their way, there would be no Israel at all. Like good little dhimmis, they blame Israel for causing all the trouble. And they don't even regard American Protestants as fellow chrstians.
Muslim Arabs can be singled out as invaders - and they were - but the Christian Arabs of Palestine/Israel have always lived there and predate the Muslim invasion. They are probably the native Jews mixed with native non Jews who converted to Christ and survived the Roman war. The Arab Christians of Bethlehem are probably the decedents of the same Jewish families who lived there in the time of Jesus.
I get the hatred you have for Christians. According to Noahide laws - Muslims ironically are automatic Noahides(guessing you are one by your profile) but Christians are idolators and need to reject Christ to qualify.
Also, I wonder if Israel Jewish animosity to Eastern Christians in Palestine/Israel has to do with the fact that those Christians are probably Jews who converted to Christ and are thus the original Jews the way Copts are the original Egyptians.
Just speculation - I don't belong to any of these groups.
PS: Again, I find it amazing how few Americans will own up to the fact that eastern Christians have suffered under American post Cold War policy - and like you just did - make it seem they have it coming for not being Southern Baptists or whatever.
Hopefully, I clarified it but I did read a report that outside of Arabs, Greeks and Italians have the most shared DNA with Hebrews/Jewish people. So it is clear to me that Jews and Hellenistic peoples intermarried as they became Christians.
Here is an interesting article that shows a Greek talk show host from Canada has Jewish DNA. That has to have come from Hellenized Jews and former Pagan Greeks intermarrying after the arrival of Christianity eliminated the religous barrier.
Most Jews spoke Greek and were culturally Hellenized (Like Paul/Saul) and what separated them from actual Greeks was religion. If both became Christian then no barriers existed between the two.

Spencer Wells: We also looked at the particular set of genetic markers you have in addition to defining you to being a member of this Haplogroup, we compared you to the entire data base, and roughly half the matches you had were Ashkenazi Jews. George: Really? Spencer Wells: So it's not definitive, but there's a chance that your dad's side of the family might have been Jewish. George: That's amazing!
