You evidently missed the definitive reply to that work, It Takes a Family by Senator Rick Santorum. It reflects what real conservatives think--and, unlike the libertarian position, it does not equate "freedom" with unrestrained-license-to-scratch-whatever-itches.
Above all, it is worth noticing because, like Goldwater's Conscience, it lays down a marker. As Goldwater repudiated Dwight Eisenhower and Richard Nixon, so Santorum repudiates Goldwater and Ronald Reagan.
