You mean put together a team that is half black, half white, half male, half female?
No, identity doesn’t predict bias. If you’ve got an acknowledged anti-Latino bias, include someone who definitely doesn’t, Latino or not. If the team ends up being all white men, that’s a pretty good warning sign you didn’t do a very good job, but it’s technically possible.
What do you mean by touched by racism?
Meaning you’ve got biases that have been installed into you by decades of exposure to racist media, housing policies, schools, family, friends, etc. It’s a nice way of saying you’re racist, but using the broad definition that includes pretty much all Americans, and doesn’t mean you’re actively trying to perpetuate these things.
