Here is an amusing online debate among some law professors on the question of same-sex marriage, hosted by the Federalist Society. Two participants are arguing the pro position, while two argue the anti (although one of them only shows up at the end to say goodbye and thank his partner for doing all the "heavy lifting").
The other anti proponent is Prof. Amy Wax, whom the Federalist Society praises for her "uniquely insightful approach."
Prof. Wax's opening salvo begins with, "a big part of the gay agenda for decades has been to repudiate what are regarded as overly restrictive expectations of monogamy and sexual fidelity," and then claiming, "the rise of multi-partner relationships as a way of life has been a major force in the decline of marriage."
Not even the other debate participants know what she's on about: "I’m afraid I've lost the thread of what all this has to do with the same-sex marriage question," says Prof. Andrew Koppelman.
Prof. Koppelman nevertheless helpfully breaks Prof. Wax's "argument" into its constituent premises and conclusions, showing both that the premises are entirely dubious and that even if they were sound, her conclusions don't follow from them anyway.
Prof. Wax responds: "Too logical for me! I guess I just don't agree that gay men will keep their non-monogamy to themselves."
Funny stuff, and worth a (quick) read.
