Two biologists have denounced "sex denialism" in a Wall Street Journal op-ed. Colin Wright, of Penn State University, and Emma Hilton, of the University of Manchester, argue that the existence of only two sexes, male and female, is a scientific fact and that transgender ideology is "an eccentric academic theory".
As they point out, even science journals are promoting a non-binary view of sex. "The idea of two sexes is simplistic," Nature declared in 2015. "Biologists now think there is a wider spectrum than that." A 2018 Scientific American article asserted that "biologists now think there is a larger spectrum than just binary female and male". And in 2018 the New York Time explained "Why Sex Is Not Binary".
Wright and Hilton describe such views as "a dangerous and anti-scientific trend towards the outright denial of biological sex". They continue, "To characterise this line of reasoning as having no basis in reality would be an egregious understatement. It is false at every conceivable scale of resolution."
This is no longer a laughing matter, they argue:
The time for politeness on this issue has passed. Biologists and medical professionals need to stand up for the empirical reality of biological sex. When authoritative scientific institutions ignore or deny empirical fact in the name of social accommodation, it is an egregious betrayal to the scientific community they represent. It undermines public trust in science, and it is dangerously harmful to those most vulnerable.
