Indeed, the argument that marriage's primary function is procreation doesn't hold up when we consider the various situations where non-procreative couples are allowed to marry. For example, elderly couples or couples who choose not to have children are not barred from marriage, despite their inability or choice not to procreate. Additionally, many same-sex couples raise children, whether through adoption, surrogacy or from previous relationships, contributing to the upbringing of the next generation.

Moreover, legalizing same-sex marriage might even have a positive effect on child adoption rates. According to a report from the Williams Institute at UCLA School of Law, same-sex couples are four times more likely than different-sex couples to be raising an adopted child. Therefore, one could argue that legalizing same-sex marriage could potentially provide more stable homes for children in need.

However, it's important to remember that procreation is not a prerequisite for marriage. The institution of marriage is about love, commitment, and mutual respect. Do you think that love and commitment should be the foundation of marriage, rather than the ability to procreate?
