Those are clearly examples of blood libel — in what sense are they not? Like how much of that is okay before it’s antisemitic hate speech? (answer: zero.)
You could but Americans aren’t Jewish so it isn’t antisemitism. When the context is different the meaning is different. That’s how words work.
But you are also saying here Israelis routinely kills children so I guess you basically just agree with the source. Good to know where you stand I guess.
That position is not anti-Zionist. It is an antisemitic trope to call the state of Israel fascist however… and untrue besides.
