Slate's Nathaniel Frank writes the single best takedown of Mark Regnerus—a lying anti-gay whore who pretends to be a social scientist—that I've seen anywhere.

The state of Michigan this week called Mark Regnerus to testify in defense of its ban on same-sex marriage. A sociologist at University of Texas at Austin, Regnerus gained notoriety after publishing a 2012 journal article arguing that children of same-sex parents faced substantial disadvantages compared to those of different-sex parents. The study catapulted him into conservative stardom, making him a credentialed mouthpiece for the claim that LGBTQ equality harms kids and can be blocked not because of anti-gay bias but out of noble concern for children and families.

Regnerus’ article made waves because it appeared to buck the trend of three decades of research showing kids with gay parents fare just as well as others. In his study and accompanying articles—including one Regnerus wrote for Slate—he touted his large, nationally representative sample size, which he said trumped the quality of research of the numerous prior studies finding that the kids are all right.

There’s one problem: Regnerus’ research doesn’t show what he says it does. Not remotely. No research ever has. Yet Regnerus, unchastened by a chorus of professional criticism correctly pointing out the obvious flaws in his work—including a formal reprimand in an audit assigned by the journal that published his piece—continues to make these groundless claims, knowing full well they are baseless. What’s worse, his role in the Michigan case is not just to oppose same-sex marriage but to argue against two-parent adoption, a position that works to keep children from having the stable, two-parent families conservatives have championed for decades. Blocking gay equality has totally trounced any alleged concern for children’s wellbeing.
