After biologist Jerry Coyne wrote an article denounced as anti-trans so the Freedom From Religion Foundation took it down.
Pinker wrote to the FFRF
I think it’s important to distinguish two things:
1. The right to bodily autonomy, an ethical issue.
2. The nature of sex in the living world, a scientific issue.
Some trans activists believe that the only way to ensure the first is to rewrite the second, imposing what we regard as fallacious and tendentious claims in defiance of our best scientific understanding. This is unfortunate for two reasons: it’s a conceptual error, confusing the moral and the empirical, and it’s counterproductive to force people to choose between trans rights and scientific reality. Those who favor scientific reality will be alienated from the cause of safeguarding trans rights.
I see FFRF as in the vanguard of separating key moral and political commitments from honest scientific inquiry (after all, a major impetus for enshrining religious doctrine such as creationism is that it is necessary for the preservation of moral values). Many people have noted that the radical factions of the trans movement have taken on some of the worst features of religion, such as the imposition of dogma and the excommunication and vilification of heretics. FFRF can be firmly on the side of trans rights without advancing tendentious (and almost certainly false) biological claims. Of course, it’s fine for views that we regard as tendentious to be expressed in FFRF forums, as long as respectful disagreements are allowed to be expressed as well.
