Women in different-sex marriages reported the highest levels of psychological distress. Men in same-sex marriages reported the lowest. Men married to women and women married to women were in the middle, recording similar levels of distress. ...

Another parenting advantage for gays and lesbians is that they seldom end up with an unintended or unwanted child, which is a risk factor for poor parenting. In 2011, the last year for which figures are available, 45 percent of pregnancies in America were unintended, and 18 percent were actually unwanted. ...

This assumes that "all of us" have "modern values" that are opposed to "traditional gender and marriage rules".
