It's worse than that actually. The respondents were the grown children of couples, at least one of which had had a same-sex relationship (or so the kids believed) at some point.
Furthermore, Benedict Carey of the New York Times noted that "About half the study participants with a gay parent, as defined in the study, were born out of wedlock and half into a traditional family that broke up. Many lived with the gay parent sporadically;" "Just three of those who had lesbian mothers lived out their entire childhood with that parent, Dr. Regnerus said; none of those whose fathers had had a same-sex relationship lived full time with their fathers through childhood."
In other words, the study compares the children of stable homes to those of not-so-stable homes, with predictable results. A proper study would compare the children of stable married hetero couples with those of stable married gay and lesbian couples.
It is not Regnerus's problem that there are no stable ss couples, or that not a single ss couple can mutually procreate.
