I don't have to imagine. I've been the first or only Black person in more than one company. I'm already the change I want. I'm just waiting for the rest of y'all (not necessarily you) to catch up.
Then you should know better than computing black:white ratios. How's that an issue? I too am a racial minority in my team and my color has never has been an issue. It becomes an issue if you consciously make it one (as you did ITT)
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.
"I too am a racial minority on my team" could mean white guy with a bunch of Asians. I'm sorry but that's not nearly the same thing as other scenarios in the US.
And plenty people of color put on race blinders or never encounter any issues, but that doesn't mean hostile environments do not exist. In my personal experience, it varies wildly from city to city and company to company. I've worked at companies that celebrate black history month and companies where white managers think it's fun to touch black women's hair.
