How old is the child again? How could that child have possibly had "years" worth of therapy? And, as I noted, many, many children block out their abuse as a defense mechanism, and these memories may take many, many, many years to emerge.
I thought you watched it... It explains all that after the first minute of the video!
By age 3 he had developed a series of problems. He was put on prozac for depression and treated for tantrums, sleeping, anxiety, ADHD, and turrets syndrome. 14 medications 17 doses a day... At age 6 a doctor during a routine physical suggested that he had Gender Identity Disorder... Hey started letting him dress like a girl and it alleviated many of the issues... (The kid actually acted happy, heaven forbid). Hormone therapy isn't something that gets started until puberty, when children often self mutilate or develop distress/depression because their body is changing in a why that they can not handle.
So lets break it down. Therapy and Medication treatment at age 3, at age 6 she is allowed to dress as a girl, in teenage years after self mutilation attempts is when hormone suppressors would start, Surgery isn't an option until late teens. There is the "Years and years" of treatment that you deny is happening.
I actually don't like medication or hormone treatments and think they should be avoided if possible. I understand that in extreme cases they are necessary but I hope we get better at solving these issues i a more natural way.
