If your only goal is ensuring that support for traditional marriage diminishes as rapidly as possible, applying constant pressure to religious individuals and institutions will probably do the job. Already, my fellow Christians are divided over these issues, and we’ll be more divided the more pressure we face. The conjugal, male-female view of marriage is too theologically rooted to disappear, but its remaining adherents can be marginalized, set against one other, and encouraged to conform.
I am being descriptive here, rather than self-pitying. Christians had plenty of opportunities — thousands of years’ worth — to treat gay people with real charity, and far too often chose intolerance. (And still do, in many instances and places.) So being marginalized, being sued, losing tax-exempt status — this will be uncomfortable, but we should keep perspective and remember our sins, and nobody should call it persecution.
But it’s still important for the winning side to recognize its power. We are not really having an argument about same-sex marriage anymore, and on the evidence of Arizona, we’re not having a negotiation. Instead, all that’s left is the timing of the final victory — and for the defeated to find out what settlement the victors will impose.
