Lots of questions yes
Although I didnt get the impression from his previous posts that he was angry or upset at his trans identity, I suspect he drove it and she either supported it willingly or went along with it out of fear given the climate.
I think its important to focus on the face he presented as female, because we what know so far about ROGD is that its born out of comorbid emotional issues/MH issues, previous trauma which in men leads to those issues being pushed outwards, so anger, confusion, hostility are centred on peers, family, society etc. Often leading to violence.
But in the climate he grew up in, validation of gender identity is immediately affirmed and rather than look at those other possible reasons for such a mixed up and confused sense of self, these were ignored.
