Because they see Israel as a settler colony. Therefore, any Jew who lives there—even if their family has resided there for generations or escaped to Israel as refugees from hostile nations—is actively participating in colonization, and deserves to be thrown out. Ironically it's often White Americans saying this, but they’ll claim that *that's* totally different somehow and that they can’t go back to Europe now, but monolingual Israelis need to go back to where they were genocided 80 years ago.
I’d guess part of it is that it’s harder to disentangle when it comes to Israel, because it’s governments have always been oppressive, even if less so than now, and it’s only come into existence more recently That being said, I know when the Russian invasion of Ukraine happened to were was a huge backlash against a lot of Russian things that had nothing to do with the current government there, and against a lot of displays of culture even from people actively opposed to the government
If whites were born in the US, parents, and grandparents in the US then how could they go back to Europe? If the connection goes back to where they don’t have family they’re close with there, how could they return? If their European lineage is broken into percentages, how would you determine where they should go? Whichever percentage is the highest?
“In AD 135, following a failed Jewish revolt, Roman Emperor Hadrian expelled the Jews from Jerusalem and decreed that the city and surrounding territory be part of a larger entity called “Syria-Palestina.” “Palestina” took its name from the coastal territory of the ancient Philistines, enemies of the Israelites (ancestors of the Jews).” The term Israel existed before Palestine. Jewish people lived in Israel before the modern state was created.
