While the premise of the letter that only marriage between a man and a woman "provides a safe environment for children (by connecting) them to their two biological parents" and that children raised by same-sex parents would fare worse later in life than those raised by heterosexual couples fails on multiple counts, the most egregious fault is using bad science (the Regnerus study) to support the argument. ("Same-sex marriage amounts to experimenting on children," Sept. 6.)
The Regnerus study itself acknowledges that what is really being compared with heterosexual families are not families headed by same-sex couples, but households in which parents broke up. This has long been established as a risk factor for poor outcomes in children.
