Healing Homosexuality: Case Stories of Reparative Therapy - Joseph Nicolosi;Lucy Freeman
Many many things in this world need to be healed.
Many are in need of healing. Cancer, heart disease, diabetes, Alzheimer's, Parkinson's, auto immune diseases just to name a minuscule few.
One thing that does not need healing is homosexuality. 
It's not a disease, it's not an illness, it needs healing about as much as having blue eyes does, or blond hair, or really big feet need it. 
I feel saddened that this is still being sold as an 'illness' by some. In this case, I can only say physician heal thyself .
