Growing up in liberal Madison, Wisconsin my neighbors Chris and Paul lived in a pink house across the street and my sister's best friend, Caitlyn, had two moms. One of my mother's favorite anecdotes to tell about my childhood was my telling her "I didn't know if I am gay yet, I have to grow up and find out" when I was five years old. Honestly, from birth I never viewed homosexuality as a choice, but merely something that couldn't be controlled and did not need to be. Shortly after I (supposedly) made this remark to my mother, my family moved to a smaller more conservative town in Wisconsin where I discovered for the first time that not everyone saw homosexuality the way my family and I did.
The debate about differences in "gay" and "straight" brains is long running. LeVay's research found measurable differences in the size of the hypothalamus between the two sets of subjects, but as his research included mostly corpses of AIDs patients his results would need to be replicated to come to any even preliminary conclusions. All sorts of myths have spread about what "causes" homosexuality, but scientists have yet to discover a dependable biological marker of sexual orientation.
Below is a clip from the Canadian sketch comedy "The Kids in the Hall" and their movie "Brain Candy." The context of the clip is that the father character has been told by his doctor that he is in denial that he is, in fact, homosexual. The doctor prescribes him "Gleemonex" to extinguish any denial and the father proceeds to blame the drug for his "gayness."Results are inconclusive to show whether or not being gay can be caused by any one specific factor, including any one difference in the brain. Yet, as people continue to place a gap between homosexuals and heterosexuals and continue to distinguish between the two, this is certainly a concept that will continue to be explored. In my opinion, it all has much more to do with an Occam's razor... The simplest explaination is to just let everyone who is gay--- BE GAY!
