Zionism, like all ethnic nationalism, is a mythological claim about an essential identity (in this case, God given) with a natural right to a territory. It, like all ethnic nationalisms, is founded on a violent cultural and ethnic othering of excluded indigenous populations.

Ah, I thought this conversation might draw a response from you, Phillip.

Once can certainly take a position that all ethnic nationalism is bad. But Antizionism is not that. It's the position that Jewish ethnic nationalism is bad. It's not criticizing the existence of Japan, or Pakistan - or and certainly not pushing back on the idea that the Palestinians constitute an independent "people." Antizionists aren't claiming that Palestinian identity is also a mythological claim of an essential identity coming with a natural right to a territory - in fact, many of them are implicitly (or often explicitly) supporting the idea of Palestinian identity and right to statehood. They're not criticizing the past of the Palestinian movement as a separatist ethno-nationalist project, with Palestinian statehood movements resisting the inclusion of the West Bank in Jordan (with political rights for Palestinian citizens) because they wanted their own ethno-nationalist organization.

Again, the problem isn't taking the position that there shouldn't be countries that are organized around a sense of identity. If someone says that they're antinationalist, that's not antisemitic. But being antizionist is being against the Jews having a country organized around a sense of identity. Not being against the idea that anyone should have a country organized around a sense of identity - the Jews. And that's the issue.
