Regnerus is the author of the discredited study which claimed that same-sex parenting harms children. Even though the study has been denounced by several sources, including Regnerus' own university, the state of Michigan called him as an expert witness.
Yesterday, he was questioned by the lawyers for the state of Michigan. If you ask me, I think he burned himself big time:
The Human Rights Campaign linked to tweets by Tresa Baldas, a staff writer for the Detroit Free Press, who noted that Regnerus admitted that he is “not a fan” of same-sex marriage and that adoption and foster-parenting are “not the ideal” and that he is “not a fan” of in vitro fertilization because in his view, it “reduces kinship.” Baldas also tweeted that Regnerus denied creating the study to derail same-sex marriage but said that a group that funded it wanted to use it before the Supreme Court.
For now, there isn't a lot of information about how he did in today's cross examination from the media because much of the attention seems to be focused on the paradox of a professor's own university AND his own department in the university - sociology - denouncing his research.
However, if the following tweets hold true, it can be assumed that Regnerus had a rough time at it.
