Another good piece in First Things is by R. R. Reno who warns that we are coming closer to realizing Plato's utopian design in which the state defines all relationships, not only political and economic, but also social and domestic, with new state backing of same-sex unions. Reno calls it the "politicization of culture."
[T]he left imagines itself expanding the scope of freedom for all. It seems all gain and no loss. In California, homosexuals can get married, and nobody is prohibiting heterosexual marriage. Everybody seems to be getting what he or she wants. But what seems is not necessarily so. When the state can rise up to redefine marriage, then the counterweight of tradition is diminished, the political instruments of power are emboldened, and our collective liberty is at peril ("Personal Freedom Without Political Liberty").
