Research has shown that same-sex relationships do not have the stability of heterosexual counterparts. 75% of same-sex couples do not stay together for more than 7 years, and monogamy is not so common. Heterosexual couples have also had some marital stability issues in recent decades, but not to this extreme. It is a myth that legalizing same-sex marriage won’t impact the heterosexual folks. Countries that have legalized same-sex marriage have seen fewer people entering ANY type of marriage, probably due to a psychological message that the procreative and unitive significance of marriage has been underminded. Children need and crave marital stability. Marrying the opposite sex “until death do us part” is a public good that remains available to all adults (even though many choose not to marry for various reasons).
