Why should a writer or for that matter film or TV producer even care what "some folks" are gonna think - it's impossible (and pointless) to please everybody. The idea that the fantasy genre is inherently European and should only consist of caucasian characters is patently absurd and untrue anyway - even CS Lewis had an Arabic-inspired protagonist (female, at that, but that's no denying a fair bit of racist sentiment in his writings too).

Btw this is an interesting read: https://www.google.com/amp/s/amp.theguardian.com/books/2021/...
