Also I don't believe there is absolutely no way to treat people for homoloveuality, the way I see it is if any researcher wants to find ways to treat homoloveuality then the public would uproar and prevent it from happening. This could explain the lack of research or knowledge on why homoloveuality happens, because it's so controversial that people are afraid to make the first step.
Many diseases currently exist and like homoloveuality it is still not known why they occur or even how to cure/treat it but even still we all know there has to be a way to fix those diseases which is why research is ongoing for them...
Many people who are gay would like to be straight, it's not easy to live being gay, I hope one day people will stop being so uptight about it and allow research to be done for those who find homoloveuality a burden on themselves. The way society is going though indicates otherwise unfortunately.
