In normalising the transgender position and exceptionalising the gender conformism of ‘being happy in the biological sex one is born with’ where sex and gender are the same, also, I think raises problems of it’s own.
So many women are not happy with the restraints their gender brings with it, culturally, historically. There would be no sexual revolution, no feminism without dissent and a redefining of gender. This is its danger. It hints at a self satisfied acceptance of all the limitations of gender expectations in society as well as reinforcing the dependency on the male. Make gender conform to sex. Don’t change sex to confirm to gender.
