Thinking of homosexuality as a disorder is in the same category as thinking the there is a man in the moon.
People just don't get it, do they? They believe the purpose of sex is reproduction and non-reproductive sex ie non-heterosexual sex, is therefore "unnatural" so a genetic disorder.
Empirical research has proved this thinking is mere superstition. Neuroscience has shown the purpose of sex is neural stability. Reproduction is an occasional side-effect. The neural change is 24/7. The reason why first the American Psychological Association and finally the World Health Organisation were forced to admit homosexuality was not a pathology was that the empirical research proved it was just a piece of heterosexual bigotry. Like white supremacists believing white people are superior.
Come out of the Dark Ages, people, and get with the programme. Read up some of the research and get educated!
