Are you saying that homosexual feelings should be supressed because they're harmful to the person? Being a chocoholic or an alcoholic are often destructive traits, either creating a istuation where the person becomes morbidly corpulant or cerosis (SP?) of the liver, respectively; both of those leading to a premature death and likely creating havoc in the lives of people around you.
Based upon your comparisons, a homosexual person is ruining his/her life, and therefore will either need to live a completely forced celibate life or force that person into a relationship with a person of the opposite sex. One would be akin to making a eunuch of the person, or forcing the person into an unnatural relationship for him/her. Three questions for you from that, Bob. Would you want your frankenfurter chopped off, leaving the beans so that you have all the desire in the world but unable to act upon them? Would you like to be forced into a sexual relationship with a man? Lastly, would you really want your son or daughter to - either unknowingly or knowingly - to marry a self-described "reformed" (likely forced reformation) homosexual?
Those are the realities you're placing upon those people.
