No, you're the one who doesn't understand how wrong you are.
Making the word "female" inclusive of male has a very deleterious effect on female people. It denies them of a meaningful word for themselves and thus the ability to describe and discuss themselves. And it denies them of single sex spaces and sports.
Women - by which I mean real women - also have the right to a dignified life. And that means not forcing them to get changed in front of males, share prison accommodation with males, discuss their experience of being raped in front of males, and compete in sports against males.
Their right to a dignified life should not be conditional on there being no males in that particular space who have arbitrarily decided that they identify as female despite meeting none of the objective criteria for being female and believe that they are entitled to access things which are for female people.
Men calling themselves "trans women" and demanding access to women's spaces is actually male entitlement writ large. They have less in common with women than most other men do.
