> While Israel is home to the largest number of Jews on Earth,

Depends on your standards for who is a Jewish person: by many standards (including those used by the Israeli Law of Return), the US has more Jewish people than Israel.

EDIT: To be clear, I am not, in noting this fact, arguing against the parent's argument that (this is a paraphrase) the opinion of the head of a state with a large Jewish population (whether or not it is actually the largest in the world) does not itself constitute the response of world Judaism, either in general or specifically as an exoneration of an alleged expression of fascist sympathies; that position is absolutely correct, irrespective of which country happens to have the largest Jewish population.

I‘m thinking further about this argument, and it makes even less sense. Judaism doesn’t have a single spiritual leader like Catholicism or Tibetan Buddhism (the Pope and the Dalai Lama respectively). This is like saying that anti-Tibetan racism can be absolved if Yan Jinhai (the chairman of Tibet Autonomous region) or Gombojavyn Zandanshatar (the prime minister of Mongolia) has said nice things about the racist because most Tibetan Buddhists live in Tibet or Mongolia.

And the elected leader of the US was also supportive of Elon’s ‘gesture’ so I guess that settles it - Jewish people worldwide, as embodied through the representative voices of their elected leaders, must agree that it was not a Nazi salute. And that firmly settles it because nobody else gets to have any opinion about it because Nazis never bothered anyone else.

/s, just in case.
