Nature and Nurture reasons of homosexuality?

Recent findings show that being “gay” is ought to ones brain anatomy. Despite advances in technology and knowledge we do not posses the key to answer how much of this is influenced by nurture, and to what degree nature affect our sexual preferences.
Neuroscientist Ivanka Savic believes she found “the most robust measure so far of cerebral differences between homosexual and heterosexual subjects”. Jerome Goldstein a well known neurologist and gay activist is interviewed about this recent findings in this article. He declares he had an attraction for the sex same at age 8. Jerome also talks about his first homosexual “experience” and how shortly after this life changing event he began his quest to fix his behavior, searching for medical and psychiatric help.
In 1991 Simon Levay was accused of being part of a “gay political agenda” after his discoveries of the dissimilarities between straight and homosexual brains particularly in the section of the hypothalamus which development is manipulated by “the levels of intrauterine testosterone”. Simon Levay discovering where found to be “nonreproducible” and “controversial” becauseof the lack of open minded individuals perhaps?
I find this article interesting and a must read for those who are still taking a prejudice stand towards homosexuals. We have traveled a long way. Up until the 1970’s homosexuality was a cause for psychiatric intervention. In some states being gay is still consider to be unacceptable neglecting the rights of many Americans whose only sin was to be a victim of nature and nurture.
