Who am I? I am not a cis woman. I am a human, an adult human female, a woman, defined as such by my biology. I accept and embrace reason, logic and science.
I do not conform to a gender stereotype and was raised both at home (despite my father) and by my school to break restrictive female stereotypes. I do not conform to a gender identity - I refuse to have a gender identity imposed on me. I cannot be cis gender and to assume I am and call me a cis woman because I am not trans, is offensive, and controlling.
My view is that there are many roles that humans can take on in life and society, and males and females, men and women should be free to take on any of those roles or combination of roles that they want to and dress however they want to, with some specific exceptions that respect the safety and dignity of others including the respect of biological sex for the protection of those that need it. When males stop committing sexual and power violence against women because of our sex and lack of relative physical strength, then the situation can be looked at again.
Accepting the existence of sexual biology and sexual biological differences is not the same as accepting gender or a gender role. Women are at risk because of our biology - in the main being less physically strong, and also by being able to be pregnant and give birth and the risk that poses to our health and because those physical states further reduce our physical strength.
Gender roles and the outward presentation throughout millennia over a range of cultures, have been in the main (there will always be some kind of rare exception) defined and controlled by men by dint of their superior physical strength for the maintenance of male power (and propensity for domination and tyranny, even over other men). The rule of logic and reason and science helps to elevate women nearer to a parity of power. Some people in power seek to stop this.
Just as I have felt that women were beginning to be taken seriously over the damaging nature of a persistent sexually charged, power culture of harrassment and assault, I do not want my status, labelling and sheer scientific definition to be (once again) redefined by a someone who is a (biological) man.
