There’s a saying, “a language is a dialect with an army and a navy.” Categories reflect social power. This is true even with fictional things. A friend was describing a fantasy novel series. I googled and found its web page and wiki.
Lo and behold, the categories in the left navigation of the wiki read:
A funny set of categories to characterize this fictional world! And there’s a backstory — some of the fans wanted to classify dragons as people, and organize them by nationality, like people. But the maintainer of the wiki wanted to keep the categories of beings separate. Leading to a heated dispute about human/dragon racism.
No word on whether there is a full-fledged dragons rights movement. Or at least a protest t-shirt.
Even more backstory. That quote about dialects? It was a quote by a yiddish scholar, made famous at a presentation in a conference in 1945, while WW2 was in progress.
