Here, let me spell it out for you. People who ask this question are usually asking it with the intention of using it as a gotcha for people against the ocupation of Palestine by saying that said person against Zionist occupation is advocating death towards Israeli citizens, and then saying that they are “antisemitic” because of it.

Now in short it is simple but see, loaded questions cannot be given simple answers because the ambiguity of simple answers to loaded and often misrepresented questions is abused by bad faith actors. I think you know this very well, and the fact you still seek a simple answer that can be misconstrued or used as a gotcha is concerning to say the least.
