Link to the ISNA's theory on how to treat an intersex cild

This morning, I found the website for the Intersex Society of North America, which includes a chart outlining their recommended approach vs the traditionally use concealment approach.  I included the link below.  Most of the site seems to recomend  allowing the intersex person to decide if tey want surgery, but one thing that struck me is that the INSA points out that they believe that:

"Physicians, researchers, and gender theorists should stop using people with intersex conditions in                                                                                            'nature/nurture' experiments or debates."

I'm particularly thrown by the assertion that gender theorists should not use intersex peopled in debate.
