The proposition 8 definition of “marriage” was misguided and led to its demise

One common argument against gay marriage, most famously used to defend California’s now defunct Proposition 8, is that marriage exists solely for a couple to have and raise children, thereby implying that biological parents are best for child welfare. Using his research into adopted parenting outcomes, Kyle Gibson argues that same-sex couples actually make excellent parents because they must put additional thought and effort into getting children in the first place. He concludes that if the advocates of Proposition 8 are truly concerned with reproduction and childrearing, they are left without a valid argument.
