I suspect that many progressives would recognize, would pushed in this way, that the case against polygamy is incredibly flimsy, almost entirely lacking in rational basis and animated by purely irrational fears and prejudice. What we’re left with is an unsatisfying patchwork of unconvincing arguments and bad ideas, ones embraced for short-term convenience at long-term cost. We must insist that rights cannot be dismissed out of short-term interests of logistics and political pragmatism. The course then, is clear: to look beyond political convenience and conservative intransigence, and begin to make the case for extending legal marriage rights to more loving and committed adults. It’s time.
