Aw, I don’t dig it

The fact that you’re conscious of these biases and are trying to take a thoughtful approach to avoiding them probably means you don’t need to worry too much about it. I think it’s probably unrealistic to be able to memorize and identify every media star, and getting some actors of a certain ethnicity confused doesn’t automatically make you racist. I mix people up all the time, regardless of their background, so don’t sweat it too much. Over time, your recognition will improve, as with any other activity. Good luck!
