Yes. It is the is-ought [1] distinction. People differences may be a biological fact, but this factual knowledge does not informs us what to do with it. We can do then anything: amplify it, suppress it, or don't care

"Natural"[2] - if it has any meaningful definition at all - is not an ethical category. Evolution is not normative.

[2] For example for a naturalist everything is natural :)

Absolutely. It maddens me how few people can see this point.
