Argument: Gay marriage is a negligible change to institution of marriage
Andrew Sullivan. "Why 'civil union' isn't marriage." The New Republic. May 8, 2000: "the inclusion of gay people is, in fact, a comparatively small change. It will affect no existing heterosexual marriage. It will mean no necessary change in religious teaching. If you calculate that gay men and women amount to about three percent of the population, it's likely they will make up perhaps one or two percent of all future civil marriages. The actual impact will be tiny. Compare it to, say, the establishment in this century of legal divorce. That change potentially affected not one percent but 100 percent of marriages and today transforms one marriage out of two. If any legal change truly represented the 'end of marriage,' it was forged in Nevada, not Vermont."
