Anybody ever thought about this angle before. It has been scientifically proven that the clitoris on womens labia is just an underdeveloped penis. A penis kept in developmental stasis because of the "Y" chromosome. When the "Y" chromosome is activated, it causes the production of estrogen instead of testosterone leading to all qualities that make us each our gender. So homosexuality is not a genetic mutation, since both genders of all human biengs carry both testosterone and estrogen. The difference is which chemical gets activated is based on whether or not the "Y" chromosome is present. This is how the argument by most people who believe that homosexuality is genetic, however that argument is flawed in that some humans are born with both sexual organs, or none at all. These people are subjected to their parents having to make a choice to determine their sexuality when they are born or shortly thereafter. The problem with this is that a great majority of these people only find this out after they themselves realize that they feel like a different gender than what they are.
Maybe this is the whole problem in the first place. Maybe at some point in time when the brain is forming, the different areas of the brain start to form into a pattern to which is the preference of the brain. Lets say for example a male, but at the same time the "Y" chromosome was present in the sperm at the time of fertilization and so the chemicals are released at the proper times to make a girl. Now you have a brain patterned after a male, but in a female body. This would eventually lead to an identity crisis at some point in time, and eventually to the person becoming a *** because of the preference for female relations. This is not the only theory, but may help explain why it is part of nature and not controllable by mankind. If the mind and body are in sync during development then the person is born heterosexual, but if the mind and body form in contradiction with one another, whether that be by accident or design, then that person becomes homosexual.
Homosexuality exists in all known living species on the planet, except plants, however they too can sometimes change gender if there is an overpopulation of one gender or another. Asexual species of plants and animals also exist on this planet. So what then, if man evolves or mutates, or whatever tag you want to confer to it, and becomes asexual as a species. Then what? Will women who can now have children on their own without the aid of males so choose to do so and make all of us obsolete. What happens if they became the majority, would then we all be labeled as freaks because we are not the "norm". So then we become ridiculed by them, hated by them or ignored by them with as much intolerance as we show those of us who are different among us now?
