Like OP and a PP, I probably had what would be diagnosed as gender dysphoria as a child.
I didn't identify with feminity, I was convinced that I had actually been born a male and my parents had decided to raise my as a girl. I was convinced I was in the wrong body.
As I grew into an adult I gained a better understanding of myself. I have PCOS, I'm large for a woman, I was always same sex attracted (becoming interested in men as I got older), and I very likely have a ND (suspected ASD & OCD).
If I was the same child, with the same feelings I had then, only being raised now - I feel my outcome would be far different from the life I have now.
I'd probably be affirmed as trans. I might end up on hormones. I might have my breasts removed.
I'd likely never meet my husband or have my children or breastfeed.
In fact, my experience as a child who was able to go through the motions of growing out of "gender dysphoria" has landed me completely on the side of GC feminism.
Enforcement of gender norms is what made me feel the way I felt.
I was bigger than the boys?
Must be a boy.
I liked boys activities?
Boy.
I liked girls?
Boy boy boy.
Removing the gender stereotypes, letting kids be kids and people be people without it meaning that there's something wrong is what we need to do.
A boy in a dress is still a boy. A woman with a moustache is still a woman.
Sex matters.
Gender doesn't.
