A author for Slate argues without reservation that the same logic behind SSM means marriage must ultimately be redefined to included polygamy -- is it still a slippery slope argument when proponents of SSM agree with you?
Recently, Tony Perkins of the Family Research Council reintroduced a tired refrain: Legalized gay marriage could lead to other legal forms of marriage disaster, such as polygamy. Rick Santorum, Bill O’Reilly, and other social conservatives have made similar claims. It’s hardly a new prediction—we’ve been hearing it for years. Gay marriage is a slippery slope! A gateway drug! If we legalize it, then what’s next? Legalized polygamy?
We can only hope.
Yes, really. While the Supreme Court and the rest of us are all focused on the human right of marriage equality, let’s not forget that the fight doesn’t end with same-sex marriage. We need to legalize polygamy, too.
... The definition of marriage is plastic. Just like heterosexual marriage is no better or worse than homosexual marriage, marriage between two consenting adults is not inherently more or less “correct” than marriage among three (or four, or six) consenting adults. Though polygamists are a minority—a tiny minority, in fact—freedom has no value unless it extends to even the smallest and most marginalized groups among us. So let’s fight for marriage equality until it extends to every same-sex couple in the United States—and then let’s keep fighting. We’re not done yet.
