They didn't realize they were confirming it, but read this from Slate:
In early childhood, in some cases. A hefty pile of research shows that boys as young as 3 years old who break from traditional gender roles have a high likelihood of becoming gay adults. Predictive behaviors include playing with Barbie dolls, shying away from roughhousing, and taking an interest in makeup and women's clothing. (Read the Explainer's take on why boys prefer to play with sticks while girls go for dolls here.) The relationship isn't one-to-one, however, and it's certainly not the case that all boys who love Barbie dolls will later identify as gay. The correlation is much weaker in the other direction: A disproportionate number of boys who don't conform to gender stereotypes turn out to be gay men, but lots of gay men played with G.I. Joe as boys and quarterbacked the high-school football team. Neither does the relationship appear to be as strong among girls. Tomboys aren't as likely to become lesbian adults.I've said for a long time that yes, lots of gay men come off as straight. But not a lot of straight men come off as gay... and are really straight. That's gaydar in action.
