Reminder that "antisemitism" was a euphemism made in the late 19th century by people who wanted to promote the ideology of hating Jewish people, to replace the previous term "Judenhaß" (meaning Jew-hatred)
Hawaiian is far from the least spoken language in the world I feel, there's many languages that are spoken in very sparse areas or by very small populations
For example, Ainu (アイヌ イタㇰ) in Japan is almost dead, with no first-language speakers and very few second language speakers, and Wymysorys (Wymysiöeryś) is only spoken by elderly people in the village of Wiliamowice, Poland
And those are only a few examples, there are a lot of languages that are barely hanging on like this
I'm not saying Hawaiian isn't endangered, it's listed as Critically Endangered, but it's one in an, unfortunately large, list of critically endangered languages
Are you thinking of Hebrew?
