As soon as I saw the link, I knew it was the study by Mark Regnerus. That study has been completely discredited as "junk" by the ASA for poor methodology and partiality. There are so many problems with the study, it's hard to know where to begin. ONE of the major methodological flaws is that Regnerus coded a parent as a single sex parent if they had EVER had a single sex relationship, regardless of whether or not it had anything to do with parenting. Next, the study did not consider whether the child had actually LIVED with the parent who had the single sex relationship... at the time of the relationship or ever. Further, the study considers the CHILD'S perception of whether or not the parent had a same-sex relationship, not the parent's. This is different than every other study performed and is based on a possible incomplete recollection. Finally, the study tends to focus on adult outcomes which may have been caused by other factors. THIS is why, in contrast to what you said, asking question about children during CHILDHOOD is the appropriate and accurate way to measure success, as this measure limits potential confounds. Regnerus himself admitted in later interviews that this coding may not have had anything to do with whether or not those parents were gay. So, your conclusions based on Regnerus's study are as irrelevant as his study is. VERY poor research on this issue, phattonez.
For more information, here are two links that discuss the discrediting:

And here is the ASA brief that shows how the study is junk. Scroll to page 16:
Nice try, but once again, you posted a study that has no credibility because of major methodological flaws.
Oh, and btw... when talking about biased researchers, Regnerus is a conservative evangelical Christian who received $700,000 to fund his study from the Witherspoon Institute... a conservative think tank opposed to SSM.
