The research thus far tends to reject the "born this way argument" because 1) while there are are likely certain bio-markers in the brains of homosexuality, we cannot use these markers to successfully predict whom is a homosexual- ergo, these markers might be biological changes being caused by homosexuality as opposed to a biological state causing homosexuality. 2.) Further, we have mapped the entire genome, and are still unable to identify the "gay" gene- thus tending to prove that being gay is not genetically influenced. Mainstream psychology has tended to prove that human sexuality is a "learned behavior" that the individual learns based upon feedback from the society in which the individual exists, with those closer to the individual usually exerting more influence. This is because an individual's normative, social, cultural, educational, and environmental characteristics all moderate the sexual drive. What we learn is not necessarily a choice though it can be. (we can choose whether or not to reject what we learn at the time we learn it.)- but acting on what we have already learned IS ALWAYS a choice. (For example although you have certainly been trained to use the toilet, you can still actively choose not to use the toliet and crap your pants.) Therefore, engaging in homosexual behavior is always a choice.
