The Heritage Foundation is making the very weird argument that allowing gay people to get married, it will cause nearly a million more abortions every year. The “reasoning” is truly loopy, with these huge leaps of logic that make no sense whatsoever.
On the surface, abortion and same-sex marriage may seem unrelated. However, as explained in an amicus brief of 100 scholars of marriage, filed in the pending Supreme Court marriage cases and summarized here, the two are closely linked in a short and simple causal chain that the Supreme Court would be wise not to set in motion.
In a nutshell: A reduction in the opposite-sex marriage rate means an increase in the percentage of women who are unmarried and who, according to all available data, have much higher abortion rates than married women. And based on past experience, institutionalizing same-sex marriage poses an enormous risk of reduced opposite-sex marriage rates.
As the amicus brief explains in detail, redefining marriage in genderless terms—which is legally necessary to permit marriage by same-sex couples—undermines the existing social norms of marriage in ways that are likely over time to reduce opposite-sex marriage rates. For example, an “any-two-adults” model of marriage implicitly tells men (and women) that a child doesn’t need a father (or mother), thereby weakening the norm of gender-diverse parenting. Other norms, such as the value of biological bonding, partner exclusivity, and reproductive postponement until marriage, will likewise crumble.
Let me translate: If we let gay people get married, straight people will suddenly decide that they don’t want to get married. Because that’s a totally rational argument, don’t you think?
