A Thought Provoking Link about Ethnicity in Writing!
I also found this post on Write World--a fantastic Tumblr you should totally check out! It features some excerpts from an ongoing discussion over there and I thought it went well with the last post here on building and researching cultures, so why not post a link to it here! You can find the post here, and here's a little sample!
"My point is: you don’t have to disrupt your setting by transposing contemporary Western categories of race developed through a history of colonization onto it in order to show diversity and complexity and the facets of the world you’re building. What constitutes racial difference isn’t going to be the same in every setting, and sometimes you’ll find in writing that racial categories aren’t actually the biggest differences between your characters." - Steampunkwyn
