Bad Study. No Biscuit!

Mark Regnerus (could his name be coincidental?) published the findings of a study on children of parents who've had same-sex relationships.  (Link is to the published article at ScienceDirect.com; original publication in Social Science Research, July 2012, 41:4, pp.752-770.)  He also has a follow-up article in Slate in which he pushes his conclusions hard.

Jed Hartman disputes the context:

Furthermore, the discussion about this child-raising issue presents a false dichotomy. It suggests that a given child has two choices: to be raised by their biological parents (who are married to each other), or to be raised by a same-sex couple. In actual reality, those are very rarely the choices. In most cases where there's a child who's about to be raised by a same-sex couple, the chance of that kid being raised by married bio-parents is extremely low. If you want to make the outcome for that kid as good as it can be, and your options are to demonize the parents or support them, which one do you think is better for that particular kid?

 PhoenixWoman disputes the definition of "same-sex relationships" (see the headline for the not-correct blooper).

When William Saletan (also in Slate) pokes at your methodology, your study design is pretty flawed.  (See Box Turtle Bulletin for serious critique.)
