Not the person you talked to but I'll join in if I may.

I've switched to using allowlist/denylist in computer contexts because more descriptive and less semantically loaded or contested. Easy win-win.

Using 'black' to refer to the color of objects is fine by me.

'Black power!' as a political slogan self-chosen by groups identifying as black is fine too, in contexts where it is used as a tool in work against existing inequalities (various caveats could be added).

As for 'white/black' as terms for entities that are colorless but inherently valenced (e.g. the items designated white are positive and the items designated black are negative, such as risks or costs), I support switching to other terms when not very costly and when newer terms are descriptive and clear. Such as switching to allowlist/denylist in the context of computers.

As for import, I don't think it is a super important change and I don't think the change would make a huge difference in terms of reducing existing racially disproportional negative outcomes in opportunity, wealth, wellbeing and health. It is only a small terminology change that there's some good reason to accept and no good reason to oppose, so I'm on board.
