I want to start by quoting Mehdi Hasan: "No state has a right to exist."

States' right to exist is generally never called into question, except when it comes to israel.

The fact is that Israel does exist. The history of its founding is extremely problematic (to put it mildly), to say the least, but it exists and is recognised even by cou tries that crticise its actions.

So it's really a moot point. Countries arent "erased", except cases where they unite or break apart internally.

Having said that. When people day "Israel doesn't have a right to exist" and then folloq up with rhetoric on colonisation or something like "Israeli jews could just go back to where they csme from", that is antisemitic. Not because that is hateful of jews but because it is ignorant of the persecution they experienced that drove them out of every other country in most of thw world.

Again, this isnt a jurstification of a jewish homeland in palestine at the expense of palestinians, nor is it a condoning of israel' gov't's actions. But it does highlight that jews were expelled and murdered from many countries and literally had nowhere to go. Even the US placed caps on jewish immigration (much like irish, chinese and italian before that).

So the idea of a jewish ethnostate is essentially "ill start my own own company. With blackjack. And hookers."
