Who is talking about skin colour here? I haven't mentioned this term a single time, instead I purposefully use the term inalienable characteristics because that covers more than just skin tone.
You're the one talking about excluding people based on skin colour, not me. That is after all what DEI ends up being: exclude those who are considered to be non-marginalised (in practice white and east-Asian, heterosexual, men) from the pool. Getting rid of DEI removes the inalienable characteristics filter so that everybody is allowed in again to compete on merit. Having a given skin tone is not a badge of merit, having achieved a given level of competence is.
Do you realise that you are the one who is turning this into a question of race and that you are the one who is willing to exclude people based on it? Read that Sowell quote again and realise you're the one he's talking about, whether you're a politico or not.
