Nothing of what you assert here has anything to do with the mechanics of homosexuality. Good and evil are ethical judgements made by the individual according to their own needs and experience. From my point of view anytime someone attempts to impose their view and desires on me, they are doing evil. Personally I found the bible contradictory and confusing. Along with some spectacular beauty and wisdom it also contains filth and mind stultifying superstition. Its confusion has been used to manipulate people and impose the will of the few upon the many. The laws of the bible are not simple. There are complex rules about cleanliness, slaughter and sexual relations. The apparently simple words of wisdom the Jesus character is reputed to have spoken are actually very complex for the analytical person. Even the "golden rule" requires us to carefully analyze our own best interests when we decide upon how to treat another person. They can be likened to Asimov's 3 laws of robotics, which while simply stated, lead to very complex decision making processes.
