In a statement released Friday, the president of the American College of Pediatricians said the Supreme Court’s decision to legalize same-sex marriage will have a significantly negative impact on children in the United States.

Dr. Michelle Cretella, president of the College, said:

[T]his is a tragic day for America’s children. The SCOTUS has just undermined the single greatest pro-child institution in the history of mankind: the natural family. Just as it did in the joint Roe v Wade and Doe v Bolton decisions, the SCOTUS has elevated and enshrined the wants of adults over the needs of children.

The College, which has members in 44 states and in several countries outside the U.S., joined in an amici brief in Obergefell v. Hodges, the case that has led to the legalization of same-sex marriage in all 50 states of the nation.

In the brief, the amici stated what is often the case when sound research is ignored by the left when it fails to support their causes:

Despite being certified by almost all major social science scholarly associations—indeed, in part because of this—the alleged scientific consensus that having two parents of the same sex is innocuous for child well-being is almost wholly without basis. All but a handful of the studies cited in support draw on small, non-random samples which cannot be extrapolated to the same-sex population at large. This limitation is repeatedly acknowledged in scientific meetings and journals, but ignored when asserted as settled findings in public or judicial advocacy.

The College itself has maintained that a significant body of research has demonstrated that “same-sex marriage deliberately deprives the child of a mother or a father, and is therefore harmful.”
