I think there is an insidiousness to our language that can help to stabilise social discrimination, and most of us (white/black, male/female) are unaware of it.

Dark mode doesn't have negative connotations. A 'blacklist' is negative selection, as opposed to a 'whitelist' which is positive selection. I didn't even realise this until I came across, and, on reflection, I agree that this is a simple change in the right direction.
