Gender ROLES are a construct of the human mind that is influenced by society. The roles and things that go along with your gender are all social. Naturally your gender is based on your sex. Though in reality is all a illusion of the mind. What is feminine and what is masculine is determined by society. You reject the role of your gender in society and how it has been defined historically.
I agree. People stole the meaning of gender,
for something it's NOT. Indeed, there WAS a
distinction between sex and gender (having to
do with the fact that someone could be male,
even without the correct genitalia), but it was
purely physical. Thus, asking someone their sex,
with only m/f was a mistake.
