Dee,
I’m as sure as I can be that we don’t become trans because of trauma. It’s the other way around.
We are born with our authentic gender pre-programmed. It’s like one’s sexuality, handedness, or other characteristics.
Some very fortunate people do not experience such trauma and shame, especially young children if they are accepted and supported by their parents and community.
For those like us it’s a struggle to not only find where we need to be on the trans spectrum but also to find self-acceptance and love. As Dara wrote in their book accomplishing this is truly a Hero’s Journey.
