I am the mother of a daughter. Boring, old-fashioned, biological females, the both of us. And I will fight tooth and nail, until my last breath, to make this world a safer place for her. For her and for all women and girls.
She deserves safe, sex segregated spaces in which to change or take care of bodily functions. She deserves privacy. All women and girls do.
She deserves the right to request a female health care provider. All women and girls do.
She deserves to have available to her women's shelters, domestic violence support and rape crisis support, should (god forbid) she ever have the need for them. Unfortunately, in this world, too many women and girls have the need for them. And all women and girls deserve to have the option available to them.
She deserves the right to name her body and her oppression in her own words. She deserves the right to talk about female-specific health and body issues without being silenced or shamed by being called a bigot. All women and girls do.
She deserves the right to be judged by the content of her character, not by the completely arbitrary and oppressive social construct of gender. There are no such things as "girl brains" and "boy brains," just human brains. There is nothing beyond physical sex that is inherent to all girls and women. There is no one right way to be a girl, and not fitting in with gender stereotypes does not make a person "really" the opposite sex. All girls and women deserve to live in a world that doesn't try to shove them into a gendered box.
This is why I'm opposed to gender ideology. For her, and all women and girls.
I have two other daughters. I protect them by making them streetwise, not banning transgender women from their spaces. The gooly man can wait outside the toilet or changing room and grab them, if that's what you're worried about.
And I will be deep in the cold, cold ground before I ever consider the solution to male violence and female oppression to be to teach my daughter to ignore boundary violations in private spaces, and to minimize harassment in public spaces.
