One last thought on this topic concerns writing what you know. Is this why I naturally think of white main characters? We often use the familiar because the whole craft of putting together a story is complicated enough on its own. Or is that a cop out? Maybe it's time to think more outside the box. For me it's a stretch that my MC is male. That takes some 'getting it right' during revisions as well.
We live in a diverse world. Fantasy worlds should also reflect diversity. How do you use diversity in your writing? Or what have you read that struck you as using diversity well?
Y'all have a great week!
