Tyler Cowen said this quote

The Christian right, which trumpets the theme of family values, damns contemporary culture for undermining older traditions. Yet many individuals from this camp are not concerned first and foremost about family values per se. Family is a codeword for constraint; families and family values place constraints on individuals more effectively than any other institution, including government. The Christian right seeks a society in which all are constrained; they reject big government for failing at constraint, and for undermining those institutions, like the family, that have a chance at succeeding.
