1) Without going into boring detail, Qazi Rahman has come under some question for misrepresenting other researchers work. While I do not mean to cast doubt on this study of its own accord and on its own merits, Rahman's characterization of the results is open to valid objection, IMHO. Rahman is clearly an adherent to the biased agenda of proving that sexual orientation is an inborn trait in both men & women.
2) It must be emphasized - as Rahman does not and as the 3 media reports I've seen on the matter do not - that the difference between straight men and gay men was not statistically significant. These results actually point toward one of the conclusions which are the subject of a much broader work that I've been engaged in for some while now (to be published some day or other):
That sexual orientation is largely predetermined amongst females but not so amongst males - or, more accurately, that biological factors exert a much stronger influence on the sexual preferences of women than of men (where the influence is marginal, at best). In short, that the mechanisms of sexual orientation are not directly comparable mirror processes between men and women (as most researchers have tended to assume - incorrectly, IMHO) or necessarily uniform within either.
That seems hardly conclusive.
Simon LeVay made a interesting observation about the emphasis on the biology of homosexuality. He noted, "...people who think that gays and lesbians are born that way are also more likely to support gay rights."Levay is often trumpeted as someone who found a gay gene. Here's what Levay said of his own research:
"It's important to stress what I didn't find. I did not prove that homosexuality is genetic, or find a genetic cause for being gay. I didn't show that gay men are born that way, the most common mistake people make in interpreting my work. Nor did I locate a gay center in the brain."The above pulled from here.
Seems irrelevant to me. Some people may be born criminally insane too. (XYY) Does it make what they do OK? Some are born with a predisposition toward alcohol addiction. Does it make regularly drinking oneself into a stupor OK?
