I think it ' s pretty obvious that it ' s a sexuality but also a mental disorder , the same said is said for homosexuality . After all , it ' s our brains and genes that make us who we are and we don ' t have control over them . You don ' t choose to be like that , you was born like that and clearly it ' s not normal or how it ' s meant to be . For example , blue eyes is a result of a simple genetic mutation that happened a long time ago , same with red hair . That said , I believe in the future these can be treated with medical science and gene therapy before before birth or after birth . I feel eugenics will become a big issue in future generations as medical science allows people to do more . But when ? I don ' t think in our life times . Just a passerby from The Donald .
