Ahh the popular "New Family Structures" study, that has been described as complete bullshit. And in a court of law was described thusly:

The brief argued that "the Regnerus study sheds no light on the parenting of stable, committed same-sex couples – as Regnerus himself acknowledges..."

There's plenty more on the criticisms of the "study", to which you are referring, here.

Want to try again, we'll call it a bonus round. I'll give you one more shot to actually prove your point.
