I'm afraid it does. If you look up gender identity, gender etc on the websites that espouse such things you'll find definitions such as that by the World Health Organisation, Or the Australian Human Rights Commission, Or Stonewall:
"Gender refers to the characteristics of women, men, girls and boys that are socially constructed. This includes norms, behaviours and roles associated with being a woman, man, girl or boy".
"Gender Refers to the way in which a person identifies or expresses their masculine or feminine characteristics."
Gender identity refers to a person’s deeply felt, internal and individual experience of gender, which may or may not correspond to the person’s physiology or designated sex at birth.
Gender identity - Refers to a person’s deeply held internal and individual feeling of gender.
Cisgender - Someone whose gender is the same as the sex they were assigned at birth.
Cisgender: denoting or relating to a person whose gender identity corresponds with the sex registered for them at birth.
What does this actually mean?
This means gender is the social stereotypes expected of one's sex.
And cisgender is a person whose internal sense of self aligns with the stereotypes expected of one's sex / whose roles and behaviours fit tose stereotypically associated with their sex.
It's really pretty sexist to call a woman that or expect her to define her identity in based on the social stereotypes that cause us so much harm.
