Seems unfair to portray it like this.
So many people who don't even consider themselves to be transgender think that modern medicine has reach a point where a penis or a vagina can be well replicated by surgery on the opposite sex. Programmes like I Am Jazz are mainstream. People don't know the reality of these medical interventions.
This man was suffering mental ill health like many people who are swept up in the transgender ideology. He thought it was what he needed to be happy. I imagine he did not think that he would be left in the state he has been left in.
