Family Research Council President Tony Perkins isn't the first or only person to posit that scientific evidence doesn't support same-sex parenting. Many a wary eye has been cast on published academic research that's found no adverse risk associated with gay parenting, under the assumption it's tainted with liberal biases [source: Kix]. But the body of research conducted on LGBT parents and their children has been overwhelmingly positive enough for a host of respected professional organizations to issue public statements giving gay parenting their stamp of approval. They include the American Medical Association, American Psychological Association, American Association for Marriage and Family Therapy, American Academy of Pediatrics, and the American Academy of Child and Adolescent Psychiatry [source: Gottleib].
Take a 2002 policy statement released by the American Academy of Pediatrics that was reaffirmed in 2010. It reiterated that, based on scientific literature, "children who grow up with one or two gay and/or lesbian parents fare as well in emotional, cognitive, social and sexual functioning as do children whose parents are heterosexual" [source: Perrin]. None of the organizations have since rescinded their positions on same-sex parenting, either, rendering the case of scant scientific evidence null and void.
