Except no one is ‘assigned a gender at birth’. Everyone has their sex observed no recorded. Nothing to do with gender.
If you are assigned anything at birth, that thing is gender. As soon as your sex is observed, society imposes stereotypes. Society assigns your gender by imposing stereotypes upon you based on your sex.
Whether or not you choose to identify with those stereotypes is another matter. The trans ideology pathologises any sense of identity that does not conform to those stereotypes.
I see you've had some pushback, but I think you made a good point. The whole point of the feminist analysis of gender is that it is an imposition pushed on people depending on their sex.
Obviously sex is determined at conception, and observed before or at birth and completely immutable, coded into every cell in our body.
But gender is most definitely 'assigned' because it's an external idea based on arbitrary and shifting norms that can certainly change throughout anyone's lifetime. That's the point of the stupid 'gender reveal' parties that shower everything in pink or blue. That's the reason people make assumptions about a baby that kicks strongly in utero being 'a footballer' if they think it's a boy, or if they know it's a girl, she'll already be being pegged as strong willed, which isn't treated the same as it would be if the child was male. All from the neutral, normal development act of moving in utero. People are assigning gender to the child based on it's sex.
Feminists have been trying to say, for a very long time, that sex is simply sex. It is an innate quality that matters for some very specific things, but not for many others. Gender is not innate. Gender is indeed assigned, and therefore should be challenged. But that means pushback against restricting women to roles and personalities and appearances based on gendered stereotypes.
It's nothing to do with the realities of sex that mean women are the sex which deal with everything associated with our reproductive system, from menstruation or the lack of it, pregnancy or the lack of it, menopause, vulnerability to rape, differences in strength to males and even being vulnerable to sex selective abortion simply because they are recognized as female embryos.
Sex is not assigned. Sex matters. Gender is assigned. Gender should be challenged.
