Gay Marriage Would Destabilize Institution of Marriage Says Canadian Attorney General

The Canadian Attorney General argued in the Halpern case:

Changing the definition of marriage to incorporate same-sex couples would
profoundly change the very essence of a fundamental societal institution. The
AGC points to no-fault divorce as an example of how changing one of the
essential features of marriage, its permanence, had the unintended result of
destabilizing the instituton with unexpectedly high divorce rates. This, it is
said, has had a destabilizing effect on the family, with adverse effects on men,
women and children. tampering with another of the core features, its opposite-sex
nature, may also have unexpected and unintended results.
