...it makes sense to consider the Canadian experience since the first Canadian court established same-sex marriage a decade ago. There are, of course, important cultural and institutional differences between the US and Canada and, as is the case in any polity, much depends upon the actions of local political and cultural actors. That is to say, it is not necessarily safe to assume that Canadian experiences will be replicated here. But they should be considered; the Canadian experience is the best available evidence of the short-term impact of same-sex marriage in a democratic society very much like America.
Civil rights and freedom of expression:
But the legal and cultural effect was much broader. What transpired was the adoption of a new orthodoxy: that same-sex relationships are, in every way, the equivalent of traditional marriage, and that same-sex marriage must therefore be treated identically to traditional marriage in law and public life.
A corollary is that anyone who rejects the new orthodoxy must be acting on the basis of bigotry and animus toward gays and lesbians. Any statement of disagreement with same-sex civil marriage is thus considered a straightforward manifestation of hatred toward a minority sexual group. Any reasoned explanation (for example, those that were offered in legal arguments that same-sex marriage is incompatible with a conception of marriage that responds to the needs of the children of the marriage for stability, fidelity, and permanence—what is sometimes called the conjugal conception of marriage), is dismissed right away as mere pretext.
At first glance, clergy and houses of worship appeared largely immune from coercion to condone or perform same-sex marriages. Indeed, this was the grand bargain of the same-sex marriage legislation—clergy would retain the right not to perform marriages that would violate their religious beliefs. Houses of worship could not be conscripted against the wishes of religious bodies.
It should have been clear from the outset just how narrow this protection is. It only prevents clergy from being coerced into performing marriage ceremonies. It does not, as we have seen, shield sermons or pastoral letters from the scrutiny of human rights commissions. It leaves congregations vulnerable to legal challenges if they refuse to rent their auxiliary facilities to same-sex couples for their ceremony receptions, or to any other organization that will use the facility to promote a view of sexuality wholly at odds with their own.
Neither does it prevent provincial and municipal governments from withholding benefits to religious congregations because of their marriage doctrine. For example, Bill 13, the same Ontario statute that compels Catholic schools to host “Gay-Straight Alliance” clubs (and to use that particular name), also prohibits public schools from renting their facilities to organizations that will not agree to a code of conduct premised on the new orthodoxy. Given that many small Christian congregations rent school auditoriums to conduct their worship services, it is easy to appreciate their vulnerability.
Slippery slope arguments:
Once one abandons a conjugal conception of marriage, and replaces it with a conception of marriage that has adult companionship as its focus, there is no principled basis for resisting the extension of marriage licenses to polygamist and polyamorist unions.
In other words, if marriage is about satisfying adult desires for companionship, and if the desires of some adults extend to more novel arrangements, how can we deny them?
a society that institutionalizes same-sex marriage needn’t necessarily institutionalize polygamy. But the example from British Columbia suggests that the only way to do so is to ignore principle. The polygamy case’s reasoning gave no convincing explanation why it would be discriminatory not to extend the marriage franchise to gays and lesbians, but not discriminatory to draw the line at polygamists and polyamorists. In fact, the judgment looks like it rests on animus toward polygamists and polyamorists, which is not a stable juridical foundation.
Marriage as an institution:
There are approximately 21,000 married same-sex couples in Canada, out of 6.29 million married couples. Same-sex couples (married and unmarried) constitute 0.8% of all couples in Canada; 9.4% of the 64,575 same-sex couples (including common-law and married) have children in the home, and 80% of these are lesbian couples. By contrast, 47.2% of heterosexual couples have children in the home. Canada stopped tracking divorce after 2008, and has never provided data on same-sex divorce.
What we can gather from these data is that same-sex marriage has not, contrary to arguments that it would, powered a resurgent marriage culture in Canada. Nor are there any census data (one way or the other) for empirical arguments tying the institutionalization of same-sex marriage to marriage stability.
