I believe that intentions matter. They matter in life and they matter in writing fiction. If you sincerely want to explore the humanity of a character who happens to be of a different race, that sincerity will shine through. Readers are so awesomely smart.
I read a beautiful and haunting anecdote in a guidebook to Rajasthan: it’s possible for children to reach the age of five without ever seeing rain, and therefore the ceilings and walls of royal children’s bedrooms were sometimes painted with cloud designs so that when it did finally rain, they would not be afraid. I wrote this image down, and everything else started spilling out.
