For the people not getting the joke, there is no such thing as Palestine. There never has been. It's a made up word, used for centuries, by anti-semitic/anti-jewish people, that wanted to pretend Israel never existed and that Jews didn't occupy that place since antiquity.

To make an analogy, it's like if I suddenly wanted to deny United States of America was a thing, and I started to unironically call the place: Burgerland.
That's how Palestine came about. If you're saying Jews are occupying Palestine, you're basically complaining that Jews are "occupying" their homeland and you're being so butthurt about Jews having a homeland that you refuse to even call it by its proper name.
