Good for you. I mean that sincerely. I've personally had my color be an issue at 2 different jobs. I left those jobs. The reason that I mention ratios is that I think that people (all people) behave better in more diverse environments. And that sometimes when ratios are skewed one way or another, those in the majority can be a bit tone deaf to others. Just an observation of human nature. If you think race is too hot of an issue, or one that you think could never be a possibility, imagine another line : gender, class, income, neighborhood, etc. I'm sure that eventually you'll see what I mean.
