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)
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.
