(Slate) -- 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.
