Actually third I read it that this person did grow up in a family that was ok with their daughter not being 'girly', they loved her as she was, allowed her to be a 'tomboy', called her boyish nicknames and were upfront about what puberty would involve. All that and she still wanted to be a man, back in the 90s when it was relatively rare.
I will never really understand gender dysphoria, or why people maim healthy bodies to try and remedy the anguish that goes on underneath but this has to be one of the most sensible things I have read on the subject in a long time. This person knows they are not really a man, knows they are doing potentially life limiting damage to themselves by using testosterone and is asking parents to step back and pause before rushing their child into medicalisation that they might well regret in a few years time.
God knows what we are storing up for our kids in years to come if we allow this to continue unchecked.
