but then is it a mental disorder, or a physical one? Is the mind wrong or the body?
Neither.. just let people be who they are.
Does a woman want to be a man because she would like to impregnate a woman, be the father of the child? or because society norms that she prefers are associated with being a man?
This is the issue with things being gender specific or applying to a certain gender. People are just people, regardless if they like pink or blue, fairies or cars.
