Blankenhorn contends that redefining marriage to encompass same-sex couples could lead to the 'deinstitutionalization' of the entire institution. By removing the inherent biological link between marriage and procreation, he argues, we risk reducing marriage to a mere contract based on emotional attachment. This could weaken its social significance and diminish its role in providing a stable structure for raising children.

The author emphasizes the unique and irreplaceable value of the biological connection between parents and children. He argues that children have a right to be raised by their own mother and father whenever possible. While acknowledging the love and commitment within same-sex couples, he questions whether same-sex marriage might inadvertently undermine the ideal of a child's right to both biological parents.

Blankenhorn stresses that the most crucial question surrounding marriage's future isn't about inclusion of same-sex couples, but rather about strengthening the institution for the benefit of children. He urges society to prioritize initiatives that bolster traditional marriage, regardless of the outcome of the same-sex marriage debate, to ensure a stable and nurturing environment for raising the next generation.
