The fact (and I regard it as fact) is that these people often do not "choose" to be homo; they are walking, talking dysfunctional products of their childhood. In that respect, they shouldn't be castigated as evil, unless they wear their dysfunction like a suit of armor and try to advocate legislation and social policy that legitimizes their dysfunction as a healthy, natural choice They are, in such cases, acting from a position of extreme pain and selfishness, if not outright evil.
It is NATURAL to BECOME a heterosexual so that is why the majority "choose" to be that--it comes down to conditioning and what you are exposed to as a young child. It is also a learned behavior, so to say.....Most male homosexuals were molested as teenagers or boys by men who recruited them for their lifestyle (see Hitler's brownshirts and their association with the youth groups in Germany--Roehm is a good example). Childhood situations can set one up to be very susceptible to that nihilistic behavior and it can be taught to one who is young and confused and has no concept of right and wrong. You especially see boys now that have no father at home who are targets for gay men. I know a man in prison, but he only got 6 years, for molesting two brothers who had "no" father and "no" religious training.
