Indeed. I wonder why it is politically incorrect to even try to research treatments for sexually based mental illnesses, but researchers are busy trying to find causes and treatments for almost any other mental illness.
Recent research has revealed that homosexuality (at least in men) may be due to epigenetic imprinting. That means that the genes are normal, but that they are modified in such a way that they are not used correctly. That suggests to me that there may be a way to modify those genes back to the normal state. That also suggests that homosexuality is caused by environmental factors; if those could be identified, a lot of mental illness could be averted.
California recently banned all gay straightening therapy. Surgical gender modification remains legal.
