that study was never successfully replicated, anon. if it were, wed be able to give brain scans to figure out if someone is gay.  dont you see the issue with all of the bogus studies youve linked? if any of them were real, wed be able to identify gay people.  yet research has consistently shown that its actually not possible to successfully identify gay people unless they tell you or you observe their social behavior.  this pretty much shows that homosexuality is a social phenomenon, likely as an adaptive mechanism to ease mate competition in a population.
