IS BEG 'GAY' A CHOICE? SCIENCE SAYS Y (BUT NOT THE WAY YOU'RE THKG)

In 1991, a study published the journal Science seemed to show that the hypothalam, which ntrols the release of sex hormon om the puary gland, gay men differs om the hypothalam straight men. Today, however, we know much more about the bra than we did when homosexualy was nsired a disease that required treatment, and the amount of knowledge that we have about the bra is creasg.

If we fe beg gay as engagg homosexual behavr (the ncept of “gay” as an inty is a Wtern cultural ncept – people who have sex wh both men and women may ll themselv gay, straight or bisexual, pendg on the l of their culture or subculture), then people stop beg gay as soon as they stop engagg this behavr. I believe that people have the right to engage any behavr that they choose, as long as their actns do not harm others, and I believe that gay sex and gay relatnships do not e harm to anyone.

If sexual preference n be altered, then people who support gay rights n’t rely on the argument that gay people should be protected om discrimatn bee gay people have no choice but to be gay – an argument that seems like an apology for homosexualy, as if homosexualy is a disease for which there is no cure.

Jt as gay people who are happy as they are should not be forced to change their sexual orientatn, gay people who want to be straight should have the right to change if they n – and the rrect word is “change” – not “cure”.

They asked more than 477, 000 participants whether they had ever had sex wh someone of the same sex, and also qutns about sexual fantasi and the gree to which they intified as gay or straight. “A lot of people want to unrstand the blogy of homosexualy, and science has lagged behd that human tert, ” says William Rice, an evolutnary geicist at the Universy of California, Santa Barbara, who also was not volved the work. “As a teenager tryg to unrstand myself and unrstand my sexualy, I looked at the ter for “the gay gene” and obvly me across Xq28, ” said Fah Sathirapongsasuti, a study -thor and senr scientist at 23andMe, which he joked once led him to believe he hered his gayns om his mother.

The rearchers had members of the same-sex muny review the study’s sign and language, and they adm that their termology and fns for gay, lbian and heterosexual do not reflect the full nature of the sexualy ntuum.

“[Our study] unrsr an important role for the environment shapg human sexual behavr and perhaps most importantly there is no sgle gay gene but rather the ntributn of many small geic effects sttered across the genome, ” Neale said. So-lled genome-wi associatn studi intified a gene lled SLITRK6, which is active a bra regn lled the diencephalon that differs size between people who are homosexual or heterosexual.

While there is no sgle “gay gene, ” there is overwhelmg evince of a blogil basis for sexual orientatn that is programmed to the bra before birth based on a mix of geics and prenatal ndns, none of which the fet choos.

Ben Carson, a retired nrosurgeon and printial hopeful, recently apologized for a statement which he said beg gay is "absolutely" a an terview on CNN, the potential 2016 Republin printial ndidate mented that "a lot of people who go to prison, go to prison straight, and when they e out they're gay, so did somethg happen while they were there?

For stance, a 2014 study the journal Psychologil Medice showed that a gene on the X chromosome (one of the sex chromosom) lled Xq28 and a gene on chromosome 8 seem to be found higher prevalence men who are gay.

But this so-lled epigenome n also be passed on om generatn to generatn, which would expla why beg gay seems to n fai, even when a sgle gene n't be such gay gen get passed down om generatn to generatn has puzzled scientists, given that gay upl nnot reproduce.
