Again, I agree that the Israeli government's treatment of Palestinians is abhorrent. That's not an anti-Semitic opinion! Claiming that Jews are not native to the Middle East and are an attempt to replace Palestinians is factually wrong, though, and does rely on anti-Semitic tropes.
(I am Jewish, but I do not support the Israeli government's treatment of Palestinians.)
You stuck an 'and' between two ideas there. Native? Sure. Not an attempt to replace Palestinians? That's an uphill argument you've carved off for yourself that runs counter to all observable facts.
May as well just fall back on the classic "it was our land first" and have done with, since honestly you're not going to come up with any moral justification that holds up any better.
It's actually quite rare to see genuine antisemitism these days. Most of what we see claimed as "antisemitism" is just vague insinuations and associations, or inventing supposed "antisemitic tropes" in what people have said.
In fact it's got to the point now where if someone is accused of antisemitism, it's best just to assume it's a malicious accusation with no substance behind it.
I mean, when you have the Zionists accusing people like Noam Chomsky and Bernie Sanders of antisemitism, you just know it's a bad faith exercise.
