Interesting that she said she started identifying as a boy shortly after her younger brother was born. I've not really thought that much about the influence of siblings on gender identity but it makes a lot of sense.
My mum always said we were "born the wrong way around". I remember my mother saying it vividly when I was 8 or 9. She said it frequently because we didn't conform to stereotypes. I point blank refused to wear pink (or black). I played with cars and my brother played with toys.
My brother now says he "just knew" he was "born in the wrong body" from about age 6 or 7. He's 3 years younger than me.
There was nothing innate about this, even though he think it is. It was my mother repeatedly saying it. My brother just doesnt remember (and never had as good a memory as me in the first place which has always been really odd - I remember from age 2, he only remembers from age 6).
I was there. I know what happened. I remember where it came from.
The sibling / parent thing and the formation of identity is important and a very overlooked area. Our identity as children isn't formed individually but also as a family unit and how we fit into that. It's symbiotic.
The whole trans ideology is founded on this idea that identity is formed and exists in isolation. It does not. Not does changing your identity an individual act, it affects the identity of others around you. For example the wife who is forced to identify as a lesbian whilst being held hostage in a heterosexual relationship.
I WISH there was something being studied on the family dynamics of families in this, because the commonalities that seem to crop up constantly are fascinating. The more I learn, the more I am convinced its societal and absolutely not innate or genetic and its something to do with how identities and relationships with others develop at key points.
