NOM (and the rest of the anti-gay world) is crowing about a study on the awfulness of gay parenting. ...Let me focus on one distinct and familiar flaw: The study compares the children of married biological parents with those from broken homes — and the study’s “lesbian mothers” that our opponents are vilifying generally weren’t married to each other; nor were the gay fathers. No, they were often in opposite-sex relationships that broke down.
The study was funded by an anti-gay group. And it's deliberately deceptive. As Live Science explains
... scientists say the research is deeply flawed, and does not measure the effect of same-sex parenting at all. The study defined same-sex parenting by asking participants if their parents had ever had same-sex relationships, and whether they had lived with the parent at that time. That led to a "hodgepodge" group of people who Regnerus then compared with kids in stable, married homes, said Judith Stacey, a sociologist at New York University who was not involved in the research.
"He doesn't have an actual category of gay parents in the project that you can isolate and say the most important thing in this kid's childhood is that they were raised by gay parents," Stacey told LiveScience. "These are kids whose parents, maybe they divorced, maybe they separated, maybe they had a scandalous affair, we just don't know."
...In contrast, a fair comparison would have matched up children of same-sex parents with children of heterosexual parents who looked otherwise similar — no extra divorces, no extra separations, no extra time in foster care for the kids, said Gary Gates, a researcher at the Williams Institute, a sexual orientation policy think tank at the University of California, Los Angeles. Instead, Regnerus categorized all people who said their parents were once in a same-sex relationship in the same group, even if those people had also experienced major childhood upheavals....
"All he found is that family instability is bad for children and that's hardly groundbreaking or new," Gates, who was not involved in the research, told LiveScience. "What I find most frustrating is that from what I could tell, he could have used his data to test the way I'm suggesting the test, and he chose not to," Gates added. "He intentionally chose a methodology that is absolutely primed to find bad outcomes in those kids."
