Stop gendering brains.
We are so sick and tired of the "male-female brain" and "cis-trans brain" arguments. Its so intersexist, altersexist, transphobic, and misogynistic.
Yes, cis endosex males and cis endosex females on average have minor differences on the size of their brains and the amount of grey matter they have. But thats on average and is based on hormone production and genetics.
Saying you can tell a male vs female brain is just as logical as trying to determine male vs female bones. Its not possible. You can guess based on averages, but those averages don't give you any precise answer.
Yes, on average trans endosex people will have different levels of corticol thickness in comparison to cis endosex people, but again, thats an average and determines nothing.
Obviously gender is a mix of social constructs and psychological factors. But not all psychological factors can be seen with a brain scan. You can have gender or sex incongruence without brain scans showing anything "different."
Bioessentialism is a load of nonsense. Stop trying to inflict binaries on everything.
