Except you come from the outrageous supposition that being gay a) can be cured and b) that gay people would wish to.   Any prevalence of depression or other issues higher than the norm in gay people comes from the stigmatisation idiots like you give them.

I purposely mentioned a medical condition through genetic history (sickle cell anaemia) and a susceptibility to what can be a lifestyle issue (type 2 diabetes, easier to catch when genetically vulnerable. ) There is no known gene for choice of partner. Some people wish fat, thin, jolly, intelligent, easy going, different gender, blondes, same gender, brunette, none at all. .... Don't try to cure lifestyle. Bad enough pharmacy companies medicalising aspects of normal behaviour without ignorant hate merchants trying it.
