Both culturally and legally marriage is a construct with a sole express purpose of endowing couples with extra resources to procreate and form families. Fags and dykes can do neither. "Gay marriage" is a grotesque imitation of a proper family at best, pedophiliac enablement mechanism at worst, and an extra tax break for narcissists burning through life on average. It is fundamentally incomparable with true marriage and using it to derive conclusion on social dynamics is flat out wrong.
