There are data that show, for instance, that daughters of lesbian mothers are more likely to aspire to professions that are traditionally considered male, like doctors or lawyers — 52 percent in one study said that was their goal, compared with 21 percent of daughters of heterosexual mothers, who are still more likely to say they want to be nurses or teachers when they grow up. (The same study found that 95 percent of boys from both types of families choose the more masculine jobs.) Girls raised by lesbians are also more likely to engage in “roughhousing” and to play with “male-gendered-type toys” than girls raised by straight mothers. And adult children of gay parents appear more likely than the average adult to work in the fields of social justice and to have more gay friends in their social mix.

Heterosexual couples might want to pay attention to these results. While the gay-marriage debate is playing out on the public stage, a more private debate is taking place in kitchens and bedrooms over who does what in a heterosexual marriage (takes out the trash, spends more time with the kids, feels free to head out with their friends for a beer). The philosophical underpinnings of both conversations — gay marriage and equality in parenting — are similar, in that both focus on equality for adults (in the case of heterosexuals, mostly wives). But even if parents who seek parity do so for their own sanity and in pursuit of their own ideals, might it not also be better for their children?

Yes, if less conventional, more tolerant children are your goal. Because if the children of gays and lesbians are different, it is presumably related to the way they were raised — by parents with a view of domestic roles that differs from most of their heterosexual peers.

Same-sex couples, it seems, are less likely to impose certain gender-based expectations on their children, says M. V. Lee Badgett, director of the Center for Public Policy and Administration at the University of Massachusetts at Amherst and author of “When Gay People Get Married: What Happens When Societies Legalize Same-Sex Marriage.” Studies of lesbian parents have found that they “are more feminist parents,” she says, “more open to girls playing with trucks and boys playing with dolls,” with fewer worries about conforming to perceived norms.

They are also, by definition, less likely to impose gender-based expectations on themselves. “Same-sex parents tend to be more equal in parenting,” Goldberg says, while noting that no generalization can apply to all parents of any sexual orientation. On the whole, though, lesbian mothers (there’s little data here on gay dads) tend not to divide chores and responsibilities according to gender-based roles, Goldberg says, “because you have taken gender out the equation. There’s much more fluidity than in many heterosexual relationships.”

So while we arguably spend too much time focusing on children, when it comes to the topic of nontraditional marriage, maybe we should start focusing on them more. One of the few parenting conversations that is not child-centric might be well served to become so. These are questions of rights and equality for adults, yes, but also questions of what is good for the kids.
