A few weeks ago, Ralph Reed stopped by the offices of the Wall Street Journal to make "The Case Against Gay Marriage" which he did by declaring that "all the statistics and data that we have" prove that children of intact, loving families to better than children who do not grow up in such families.
Reed proceeded to cite some unnamed CEO who claimed to have studied the most productive staff in the company and discovered that "the number one determinant of how hard they worked and how dedicated they were" was coming from an intact, loving family.
Of course, that might lead one to ask how exactly that is supposed to be an argument against gay marriage, since gay marriage would only lead to the creation of more intact, loving families, but Reed wasn't buying it because "we have not tested that thesis on a national level."
Apparently the anecdotal evidence that Reed gleaned from some anonymous CEO was very convincing but the idea that gay families could also produce productive, hard working citizens was too untested and so it would be dangerous to "tinker" with the institution of marriage so "willy-nilly":
