Daphne Joel is not nearly the only neuroscientist that criticizes stereotypical ideas about brain sex. The very black and white, women are from venus and men are from mars vision of male/female brains has been even more strongly critiqued in the last decades with the discovery that many areas of the brain are not sexually dimorphic. I think you are also misrepresenting that stance, which is that radfems and those neuroscientists don't deny sex differences, but the way that they are grossly distorted in popular culture, from the 1800s where they found women's brains to be lighter and therefore it was decided it made them inferior, to the point that men think they have female brains if they have traits associated with women.
