I think I found another blogger who agrees with you:
“I haven’t read the study, which comes out in July in the journal Pediatrics, but I’d venture that childhood outcomes have little to do with sexual orientation per se. For gay parents, having a child is a more “involved,” and in most cases expensive, process. It generally involves hefty adoption fees or paying for assisted reproduction technology. So those who have children are a self-selecting group: They want children and are wealthy enough to either meet adoption requirements – and pay the fees – or pay large medical bills. It’s no surprise that the lesbian parents in the study were very involved.”
YIKES! The harsh comment under the article I linked to follows:
“Isn’t it wonderful that most children of lesbian parents have no idea about ther other half? One half of their genetic makeup is a freeloader psychopath sperm donor (only a freeloader would not contribute financially or otherwise and abandon his offspring), and the other half is a selfish reproducer who thinks that her desire to reproduce trumps her offspring’s right to know and have a good father who is involved in their lives. By sanctioning conception via donated sperm and eggs, by virtue of passing selfish freeloader psychopath genes, the society is signifiantly increasing the percentage of those within it that have these attributes.”
