you're saying feminists should be fighting for those who perform feminity, rather than those who are female? No that is not what am saying. Each sex has been ascribed a gender. We all know which gender belongs to which sex. Gender is manmade idea, while sex is natural occurrence in the human body. We use gender to segregate and mistreat females in our society. When a feminist is fighting against injustice, they are fighting against preconceived idea of what a female is through what characteristics we put forward as woman.
Feminist are not just fighting how females are treated in regards to what their biology can do ( ie giving birth ) but also what you wear and on how it can define you as a female person. So if a man was able to have the complete look with what we conceive to be the standard woman, they would receive sexism and will be judged the same way a human female would if they where dressed the same way. It's what is in front of the sexist. They see what looks like a woman and by that they have stereotypes of what women are.
A Person who's body was designed to produce eggs, things may have gone wrong to affect this ability but it was the intent and that is the human female. Humans separate us from being referred to as amphibians or any other living female species out there.
I have a vague idea of what cis is because I have seen it debated on Mn. I have no interest in calling my female species cis women. That is just adding another label on top of what is already disadvantaging.
^*Sex" refers to the biological and physiological characteristics that define men and women.
"Gender" refers to the socially constructed roles, behaviours, activities, and attributes that a given society considers appropriate for men and women.*^
This is what I have been trying to say from the beginning. These roles, behaviours, activities change over time. They are relative and not absolute. It's society that makes it normal. When in America football is a girls sport and in the uk it's seen as boys sport. That is relative. What feminist would do is try and fight for the rights for women to be able to play the sport in the uk without it being deemed macho and they can earn the same amount according to their standard.
The website you got from describes the way i have been putting it forward.
