So Bradley Manning wants to live as a woman.
To which I say fine. But not until Manning serves his time.
Manning committed and was convicted of various acts of espionage. He must be punished for these acts. Part of that punishment is being deprived of the freedom to live life as he chooses.
Although Manning was sentenced to 35 years in prison, chances are he will be out by 2021 with good behavior. Once Manning is freed, he can obtain gender reassignment therapy and call himself Chelsea, Hillary or whatever name suits his fancy.
But until then Bradley Manning has to take his punishment like a man.
