Russell Snell, associate professor of philosophy and director of the philosophy program at Eastern University reviews the new book "What is Marriage? One Man One Woman: A Defense" and also focuses on the threat posed to freedom by those who would redefine marriage:

"...Freedom is also at risk. If the law withdrew its support of conjugal marriage, the state would “imply that the conjugal view makes arbitrary distinctions,” and supporters of conjugal marriage could not be viewed as anything other than unreasonable “champions of invidious discrimination,” with encroachment on conscience quite likely. Already defenders of the conjugal view are likened to racist supporters of antimiscegenation laws, and examples grow of their lost employment, eroding freedoms, and social stigmatization. Nor does the allegedly “conservative” claim that the revisionist view imposes marital norms on more relationships address that view’s arbitrariness or provide any reason why traditional marriage norms are binding once divorced from the conjugal view. The reality that they are not binding is supported with ample evidence of the high value placed on “openness” and “flexibility” among proponents of same-sex marriage."
