Israel has no right to exist, it is stolen land that needs to be returned
You could say that about nearly every country. Perhaps white people need to leave the US and Australia. Perhaps anybody with Anglo-Saxon genetics needs to leave the British Isles and return to the area around Germany and Denmark.
I think Israel's current far-right government is terrible and has committed genocide, but I don't think that means Israel needs to stop existing as a country altogether. Germany didn't stop existing after WW2, although of course it was split into two parts.
I think some people don't like the idea of an explicitly Jewish state existing, but if someone uses that logic, then surely they would have to also object to every explicitly Muslim state: Iran, Saudi Arabia, and so on.
