Wikipedia gives a great overview on this topic: en.wikipedia.org/wiki/LGBT_parenting
quote: "Scientific research has been generally consistent in showing that gay and lesbian parents are as fit and capable as heterosexual parents, and their children are as psychologically healthy and well-adjusted as children reared by heterosexual parents. Major associations of mental health professionals in the U.S., Canada, and Australia have not identified credible empirical research that suggests otherwise."
