Personally I agree with Coyne and Dawkins complaints about the article critiquing the language of fitness and adaptation...oh wait...sorry I was reading a Lewontin article
More seriously, critiques of adaptation and fitness have a long tradition in evolutionary biology. You don't have to agree with every part of them to gain from reading them.
It's very fair to wonder about how much of our field's language & the way we think has been shaped by the history of eugenics & ableism. Such conversations will be uncomfortable and that's good.
