Main Characters Defaulting to Same Race
I don’t think it’s an issue in need of changing; only if you want to. I’m not gonna wag my finger at anyone if their MCs tend to always be Black, Japanese, or any consistent racially/ethnically diverse person.
I also happen to default my writing with Black heroines, being a Black woman and wanting representation for myself, with a diverse cast surrounding her, but sometimes I explore my choices deeper and question “what if she were… Indian?” and then picture her as Indian, how the dynamic might change physically, culturally, etc then I mentally run herthrough events in my story and see how it feels.
Sometimes it clicks and that’s how I
keep her. Sometimes I think of what other race or ethnicity she might be, always
considering the intersections that exist as I don’t want to walk her into a
problematic role. But this is just my method.
So my advice is you don’t have to stop making your MC Black
females as there’s nothing wrong with that, but if you’d like to, don’t hesitate
to brainstorm what other possible race or ethnicity she could be.
