Saletan looks at the new study on the genetics of homosexuality I cited here:
You don’t need to worry that gay teachers or television characters will "convert" hordes of boys. Sexually antagonistic selection is self-limiting and impervious to postnatal cultural factors. The authors’ computations show no scenario in which male homosexuality spreads throughout a population.
And the Vatican – surprise! – is just smearing a difference as a disorder:
The study’s press release concludes that "homosexuality should not be viewed as a detrimental trait (due to the reduced male fecundity it entails), but, rather, should be considered within the wider evolutionary framework of a characteristic with gender-specific benefits."
