Philosemitism is often used as a term by Jews, who don’t want to be conflated with Israel. See for instance the explainer by the Diaspora Alliance, who see German political philosemitism as performative and often complemented by antisemitism.

Summary: Philosemitism, like antisemitism, others Jews. Political philosemitism invokes support for Jews and Israel that is often a cover for advancing repressive policies.

⁄ A. Philosemitism does not cancel out antisemitism — and is often complemented by it
⁄ B. Philosemitism mimics antisemitism by making Jews the avatar for political or social crises — but does so in the name of protecting them
⁄ C. As an electoral strategy, philosemitism serves to either solidify or expand political bases of support

Whatever. I don’t think philosemitism is really too extreme a position for a memorial site on the ground of a former extinction camp. They’re certainly not representing a neutral position.
