Gay parents "tend to be more motivated, more committed than heterosexual parents on average, because they chose to be parents," said Abbie Goldberg, a psychologist at Clark University in Massachusetts who researches gay and lesbian parenting. Gays and lesbians rarely become parents by accident, compared with an almost 50 percent accidental pregnancy rate among heterosexuals, Goldberg said. "That translates to greater commitment on average and more involvement."And while research indicates that kids of gay parents show few differences in achievement, mental health, social functioning and other measures, these kids may have the advantage of open-mindedness, tolerance and role models for equitable relationships, according to some research. Not only that, but gays and lesbians are likely to provide homes for difficult-to-place children in the foster system, studies show. (Of course, this isn't to say that heterosexual parents can't bring these same qualities to the parenting table.)

I think this is an important research stating the obvious.
