I see no difference between this guy wanting to cut off his arm and another guy wanting to mutilate himself between the legs because he feels like a woman. Both probably have some sort of chemical imbalance that is not yet well understood.
In a way, aren't we all chemical imbalances?
Yes, but to what point? A lot of mental health issues result from chemical imbalances, but it's well understood and people are helped with medication or by other means - not from having to undergo a major physical transformation.
Wow, I'm feel privileged that we have a medical expert on the forum! I mean your advice is directly contradicted by basically every association of doctors and pschyatrists out there, but what do those hacks know anyway? They clearly don't have your cunning intuition to make didactic statements based on absolutely no evidence. Give this man a Nobel Prize, friends.
