OP, you’re the one who has been talking about barbie dolls and you have posted a video where the trans child lists gender stereotypes.
It is interesting that you have found a passing reference to trans tomboys, but that really isn’t the main narrative is it??
You didn’t answer my question before but this really gets to the point you’re making with trans tomboys (I think).
In a child of the age that typically plays with barbies dolls, what is the difference between gendered behaviour and gender identity??
