I'm autistic and I think I might be gender critical as much as I understand it.
When I was a child I thought I was a boy for a while, but in those days (1970s) I think that was pretty normal - there were lots of tomboys. But I always thought being a woman/girl was about biology, and that gender was all the stereotypes people/society created about male and female, but not fixed facts.
I can imagine if I was young now I might think I was trans and get very invested in the identity and ideology. I've had periods in my life where I've got hugely involved, practically and emotionally, in various political/justice campaigns e.g. for a while my whole life was about a particular environmental issue - I spent my time either researching it, campaigning, doing practical action, discussing with others in the campaign. My identity was very tied to it and it felt like I was doing something really important. I imagine being in the trans movement now might feel like that.
But my understanding is that most trans people don't seek surgery and are living with their birth biology, so why does there need to be any association claimed between the way a person chooses to dress and behave and their biological sex? I don't really care about what pronouns, clothes, etc other people choose, but stuff like make up, heels, skirts and subordination are definitely not an intrinsic part of being female, and I wonder if there are young women who are absorbing that message and thinking "I must be trans" because they don't fit the 'female' stereotypes.
For people who are (presumably happily) living with their own biology, is it naive to wonder why we can't all just dress and behave in the way that we find appealing without needing to link that to biological sex? Am I GC or have I misunderstood the whole debate?
