There is an article posted in a scientific journal which the TRAs like to reference as proof that sexual dimorphism in humans isn't real. The article is written by a biologist but the article itself is not scientific at all. It is written as an opinion piece expressing how recognizing human biology is too harmful to transgender people so the claim is made that biologists should willfully ignore the science and use all vocabulary the TRAs want because speaking plainly causes so much harm etc etc.
