But there's an important caveat that the gay activists don't mention when trumpeting this good news.
The first raters judged targets' sexual orientations from unedited videos and from partial information extracted from the videos (e.g., video without sound for ratings of movement or sound without picture for ratings of speech).
Science, though, is late to linking sexuality with gender expression.
Karl Heinrich Ulrichs, the first openly gay man, argued in pamphlets starting in 1864 that " an Urning [his coinage for a gay male] is not a man, but is a type of hermaphrodite, a man-woman with the sexual orientation of a woman," a "third sex." Ulrichs used the Latin phrase anima muliebris virili corpore inclusa (the soul of a woman in the body of man) to sum up his theory: "Distinct from the feminine persuasion of our sexual drive, we Urnings have still another feminine trait in us which, so it seems to me, offers the most positive proof that nature developed the physical male germ in us, yet mentally, the feminine one." A century before Ulrichs, molly houses existed in 18th century England whose participants engaged in feminine behavior.
When Stahl came for a visit, Jared was eager to show her his G.  Subsequently, we recruited homosexual and heterosexual adults to rate the degree of gender nonconformity from both the childhood and the adult video clips.
The raters found that "prehomosexual children were significantly more gender nonconforming than preheterosexual children" and that these differences persisted into adulthood.
