I’ve been called that for wanting a period piece to look like it’s supposed to. Like you said, prior to the diversity worship I was willing to try anything out but now I’m very wary or need recommendations from a trusted source on things. I got attacked for saying the little mermaid casting was dumb and it would’ve been easy to write a story about a mermaid. Heck, I know there is folklore from Africa about sea creatures. Just use that.
