I think this is a super pertinent question right now, and one that, as a white person, I wonder about too. I'm glad you are getting some thoughtful answers in with the bullocks.
Of course there is no cut and dry answer! This is such a complicated topic, made up of people's feelings and thoughts. As far as I have learned, being willing to ask, try for respect, make mistakes, and recieve feedback and answers is right on. The fact that you are asking the question is a good sign! My advise is to keep asking as your character develops. It's awesome that this character excites you.
@llLeoll - no need to read my work :) But thats a sweet reward you are offering.
