It's normalcy is determined by the fact that it inherently does not cause any physical or mental harm to those that share it's characteristics. It presents no handicap, well, other than the nonsense of c*nt's like yourself.<quoted text>
In spite of 'psychology, psychiatry, biology and sociology' not knowing what causes homosexuality, you claim they can determine the normalcy?
Do you really think anyone believes that nonsense.
All mainstream medical and mental health organizations have concluded that varying sexual orientations represent normal forms of human experience. The origin is irrelevant. And their opinions are more important than yours.
BTW, right handedness, left handedness, and ambidextrousness, despite that psychology, psychiatry, biology and sociaology not knowing what causes them are also all perfectly normal.
Normal isn't determined by origins.
