А вот это далеко не очевидно, по крайней мере некоторые ученые с этим не согласны. Посмотри на табличку из недавнего исследования Техасского Университета на эту тему :
How different are the adult children of parents who have same-sex relationships? Findings from the New Family Structures Study

Единственный плюс однополых семей - дети, выросшие в семье гомосексуалистов (не лесбиянок!) чаще ходят на выборы.

Вполне возможно, они также чаще предпочитают хоккей балету, и пиво шоппингу.
Наверное, можно согласиться с тем, что крепкая и любящая однополая семья для ребенка лучше, чем разваливающаяся и нефункциональная двуполая. Но ведь выбор обычно стоит не так. В развитых странах ребенка из нефункциональной семьи обычно помещают под опеку в семью опекунов (так называемую foster family), где он ожидает усыновления в постоянную семью. И вот в такой ситуации уравнивание в правах однополых и двуполых семей совершенно не выглядит очевидным.
Вот еще немного аргументов в пользу двуполых семей из статьи Trayce Hansen, Ph.D. :
As mental health professionals, it’s our ethical and moral obligation to support policies that are in the best interest of those we serve, particularly those who are most vulnerable—namely, children. Same-sex marriage may be in the best interest of adult homosexuals who yearn for social and legal recognition of their unions, but it’s not in the best interest of children.
Proponents of same-sex marriage believe love is all children really need. Based on that supposition, they conclude it’s just as good for children to be raised by loving parents of the same sex, as by loving parents of the opposite sex. But that basic assumption—and all that flows from it—is naively simplistic and denies the complex nature and core needs of human beings.
According to decades of research, the ideal family structure for children is a two-parent, mother-father family.(1,2,3) That research consistently shows that children raised in such families are more likely to thrive—psychologically, mentally, and physically—than children reared in any other kind of family configuration.
Extensive research also reveals that not only mothers, but also fathers, are critical to the healthy development of children. Swedish researchers reviewed the best longitudinal studies from around the world that assessed the effects of fathers on children’s development. Their review spanned 20 years of studies and included over 22,000 children, and found that fathers reduce behavioral problems in boys and psychological problems in girls, enhance cognitive development, and decrease delinquency.(4)
It’s clear that children benefit from having both a male and female parent. Recent medical research confirms genetically determined differences between men and women and those fundamental differences help explain why mothers and fathers bring unique characteristics to parenting that can’t be replicated by the other sex. Mothers and fathers simply aren’t interchangeable. Two women can both be good mothers, but neither can be a good father. One-sex parenting, whether by a single parent or a homosexual couple, deprives children of the full range of parenting offered by dual-sex couples.
