• “Same-sex marriage” communicates that a woman is a half-woman. That in marriage a woman’s own womanhood is incomplete. “You’re not enough to represent whole womanhood in this marriage.”
• Or worse, instead of honoring the essential role women have in marriage—an essentially gender-diverse institution—”same-sex marriage” communicates that women are expendable, superfluous, and undesirable to some marriages.
• Similarly, polygamy treats women as less than whole women. It is like saying to a woman, “You’re not enough to complement a man or represent the unique contribution of woman in this marriage. You’re a half-woman, or a third of a woman. So I need more than you.”

Polygamy also makes a mockery of marital love’s exclusivity: “I exclusively bind myself to you, and I exclusively bind myself to you, and I exclusively bind myself to you…”

It’s like saying to three women, “You’re my favorite, and your my favorite, and your my favorite.”

The philosophy used to support same-sex marriage often says that womanhood isn’t real: That it is just a social construct. That it is nothing specific; it’s anything we want it to be. That is has no morally significant purpose, design, or essence, or ontology. That some children should be “liberated” from the supposedly inherently awful state of being born as a woman.
