One is likely the majority, the other the minority.

It doesn’t negate any behaviour based on bias but would require an honest reflection on the unconscious biases existing in the workplace prior to this.

Aren't they both the minority in their respective situations ?

One way to look at it is minority groups who can’t turn off being visible minorities can be different than people who may be minorities in a a few areas of life but still have access to benefit from privilege in others.

I dont believe its good to narrow down minority status into something which is only visible, feels a bit ableist.
