For those who haven’t been paying attention, Last shows that “the same-sex marriage movement is interested in a great deal more than just the freedom to form marital unions”:
It is also interested, quite keenly, in punishing dissenters. But the ambitions of the movement go further than that, even. It’s about revisiting legal notions of freedom of speech and association, constitutional protections for religious freedom, and cultural norms concerning the family.
Last asks: “Remember when proponents of same-sex marriage mocked people who suggested that creating a right to same-sex ‘marriage’ might weaken the institution of marriage itself?” He points out that candid gay activists acknowledge that non-monogamy is rampant in gay marriages and that the marriage redefinition they are seeking will undermine the norm of marital monogamy . . ."
