Brainsex now is just as sexist as brainsex was in the 1800s. However, the sexism of brainsex is not my topic today. As someone who values critical inquiry, what bothers me even more than the blatant sexism is the sheer level of anti-science thinking required to accept that transgenderism proves brainsex when in fact it disproves brainsex
If your thesis is that male humans and female humans have different brains, you must define male and female and those definitions must STICK. Male = sperm producer. Female = ova producer. The existence of males/sperm-producers who supposedly have "ladybrain" means THAT'S NOT A LADYBRAIN.
THIS COPING METHOD OF CHANGING YOUR DEFINITIONS TO DISGUISE THE FAILURE OF YOUR HYPOTHESIS IS NOT COMPATIBLE WITH THE SCIENTIFIC METHOD.
P.S. for those who think the existence of (sexist, anti-scientific) brainsex theory differentiates transgenderism from transracialism/#wrongskin, I give you THE HISTORY OF BRAINRACE THEORY.
Stop bending yourselves in pretzels and just accept that human personality isn't innately sexed any more than it is innately racialized.
