Being gay is a not a choice!

Theories of causation for homosexuality have shifted dramatically in the past 100 years. Early psychologists believed that early childhood trauma caused homosexual feelings to develop. Specifically, Freud proposed that a weak father and an overbearing mother caused a person to "stall" in the phallic stage of childhood development. Subsequent studies have shown there is no association between any parenting style or early childhood experiences that leads to homosexuality. According to the American Psychiatric Association No specific psychosocial or family dynamic cause for homosexuality has been identified, including histories of childhood sexual abuse. Sexual abuse does not appear to be more prevalent in children who grow up to identify as gay, lesbian, or bisexual, than in children who identify as heterosexual. Rather, all of the peer-reviewed literature is converging on the opinion that sexual orientation has a strongly genetic causation. This is not meant to imply that sexual orientation is completely determined by genes. It seems there is a complex interaction between biology and the environment to produce sexual orientation. In insects, same-gender sexual mating is induced from altering genes alone, thus indicating a 100% biological causatoin for sexual orientation in simple species. For lower mammals, like rats, same-sex mating behaviors will occur simply by putting a female "smell" on a male rat. "Lesbian" and "gay" rats, guinea pigs, sheep, zebra finches (just after hatching) and monkeys can be produced simply by altering prenatal androgen levels (natural hormones that bathe the fetus in utero) in the mother, in a process called behavioral defeminization and behavioral demasculinization. It is currently believed that In vertebrate model systems, a single [prenatal] factor-the steroid hormone testosterone-accounts for most, and perhaps all, of the known sex differences in neural structure and behavior. . . . Events triggered by testosterone masculinize the developing and adult nervous system, [to] promote male behaviors and suppress female behaviors. In the animal kingdom, same-sex mating, including life-time pairing, is not uncommon, presumably caused by mechanisms such as these. Hundreds of zoological studies have found evidence of such pairings in the wild, including, for example, the widely publicized "gay" penguins in both the New York and Berlin zoos. In humans, socialization makes the development of sexual orientation much more complex. However, the prenatal biological process is identical. While, in most instances, sexual development of the body and the brain occurs without discrepancy, in some instances prenatal androgen levels change in the middle of this process, causing a dichotomy in the affected individual. For example, in congenital adrenal hyperplasia, the early process of physical sexualization takes place as expected in the female. However, later in development, the adrenal glands begin producing excess testosterone, causing the brain to become masculinized. Almost half of this population become homosexual or bisexual. It is believed that similar processes are the cause of homosexuality in the general population. While the pro-amendment testimony is correct, that "there are no replicated studies proving that homosexuality is caused by biological factors," there is also no disagreement at this point in the medical, psychological and biological communities that biology is a crucial dimension to the process of human homosexuality, just as it is the sole cause of homosexuality in all lower species. There are no peer-reviewed studies that any longer explore purely, or even mostly, psychological causes for homosexuality in humans. The convergence of many decades of research, as well as theory, all point to, by far, biology as a primary factor in human sexual orientation. While we know that biological factors do not act as the sole cause of homosexuality, it is accepted as the primary cause. While many studies support this idea, there are no current studies that contradict this belief.
