A wisdom greater than psychological science may be helpful here, specifically Pope Benedict’s on understanding the vital complimentary of a husband and a wife that is for the healthy development of a children.

Pope Benedict has described the “male genius” and the “female genius” in The Collaboration of Men and Women in the Church. He wrote in regard to the “male genius” that, “Greater distance from process of gestation and birth enables him to act more calmly on behalf of life; he acts to protect life and guarantee its future; he is a father in a physical and spiritual sense and he is called to be strong, firm, reliable and trustworthy.”

In describing the “female genius,” he wrote, “She has a special capacity to show love, a delicate sensitivity to the needs of others, a special capacity for the other and understanding of inner conflicts in others.”

I repeat my question: should purportedly scientific claims about what the studies show on the fitness of gay couples to raise children be based on studies of gay couples raising children? Yes or no?

The fathers in that study were married to the mothers.

That is not a study of the outcomes of being raised by gay couples, it is a study of the outcome of being raised by a mixed orientation marriage. You are comparing apples to oranges. It is one thing for scholars to disagree on interpretation of data. It is quite another thing and much rarer, as you well know, for one scholar to accuse another of misrepresenting her work.

Let me ask you a very simple question: should purportedly scientific claims about what the studies show on the fitness of gay couples to raise children be based on studies of gay couples raising children? Yes or no?

I, I ought to note, am in agreement that it is a bad idea for gay men to marry women. That is one reason why I support marriage equality.
