Anti-Zionism as a container for antisemitic content
Antisemitism has never operated in a stable form. It adapts to the available idiom — the accusations that are socially permissible in a given era. The content is largely continuous across centuries. The framing changes to fit whatever will not trigger social sanctions.
The logical test for whether anti-Zionism functions as a container for antisemitic content is the universal principle test: any principle applied exclusively to Jewish nationalism but not to comparable nationalist movements is not a principle — it is a conclusion about Jews.
Approximately 95% of Jews worldwide identify as Zionist in the minimal sense of supporting Jewish self-determination in their historical homeland. Anti-Zionism therefore targets the defining self-identification of the overwhelming majority of the world's Jews. An ideology that opposes the national self-determination of one specific ethnic and religious group while supporting it for all others is not a neutral political position.
If the objection to Zionism were a principled objection to ethnic nationalism, it would apply to Kurdish, Armenian, and Tibetan nationalism with equal force. It does not. The selective application of opposition to Jewish nationalism while supporting structurally equivalent nationalisms for other groups is the evidence that the objection is not about nationalism in general — it is about Jews specifically.
