If one accepts evolution as a necessary and inevitable force in nature then on what basis would a person object to ‘weeding out the unfit’?

“If one accepts evolution as a necessary and inevitable force in nature then on what basis would a person object to ‘weeding out the unfit’?”

It rather depends upon whom it is doing the defining of “unfit.” Whether or not “one accepts evolution as a necessary and inevitable force in nature.” Don’t you think?
For instance, we can imagine that most 0bmatrons would be pleased to define Conservative Christians, and most Conservatives in general, as “unfit.”

Surely, other examples come easily to mind.
