Such states might start being more intentional about celebrating motherhood and responsible fatherhood through cultural messaging on social media, public service announcements, and in the schools. State public television could be enlisted to produce pro-family programming. States could seek to attract churches aligned with a family-friendly mission through targeted advertising and robust law enforcement.
All the while, lefties will moan that the state makes them uncomfortable and then threaten to leave. Plenty of U-Haul trucks are available! Family-friendly citizens in; other citizens out.
Families do not exist to support the state. The State exists to support the family, which exists to support the individual, which comprise families. Family is the natural order of humanity. Our modern government seeks to de-humanize us. Until we recognize this, our reactions will amount only to re-arranging the deck chairs on the ship of state.
