I sincerely doubt that the child had any real independent input in this matter; getting “beat up” by the other children wouldn’t do anything but hurt and confuse him further.
The idea that somehow this child made this choice - at the tender age of nine - is precisely the propaganda that his handlers want others to accept. Adults would do well to remember that this child CANNOT make this choice on his own; only his “counselors” and parents can encourage and authorize this “gender change”. The decision lies with them.
That’s it exactly.
