Actually the present statist style of government is not particularly interested in strong or stable family relationships. That's why they subsidize and encourage single parent families, and that's one reason there has been a steady increase in the number of children born outside of marriage.
To a government seeking to expand its role in society replacing the family as the primary caregiver is a wonderful tactic. We saw that on display in the last presidential election, where Democrats campaigned on how they, once in power, would take care of women's needs. Notice how our current president never takes to the bully pulpit to encourage young women to get married before having children.
So as it stands today I don't think you can characterize the government as a supporter of family life. They may want a stable society of people dependent on government, but they most certainly don't want a stable, family based society with little need for a strong central government. Recent actions by the Justice Department underscore the animosity of the federal government to families. Amazingly, when we have millions of illegal immigrants, the DOJ is litigating against a family of Swedish homeschoolers who are seeking asylum in the USA so they can continue to home school.
Given the hostility of government towards traditional families and religious institutions, it would be better if they simply had nothing to do with marriage. After all, why should any adult have to ask permission from the government to get married?
The first step in promoting a stable society is to reduce the negative effects of a large, overbearing government which is damaging the very institutions, like marriage and families, that society really depends on.
The current 1984 style fascists are promoting “anti-families”.
The goal is dependence on nothing and no one but the State.
“Government has no interest in promoting a stable society?”
The person who defines the meaning of the terms gets to control the outcome of the debate. With 74% of black children being born to an unmarried mother, what is “stability” in this context? Nine out of ten young black men who are murdered die at the hands of another back man.
Indeed, one third of all black males who dropped out of high school are in prison, where society is stable.
Clearly for this demographic, they are going their own way and the fruits are horrible. They clearly don’t care about the institution of marriage. They seemingly have an inverted relationship to it compared to the homosexual demographic. But in the end the result is the same: the institution of marriage is destroyed. Maybe that is the higher goal all along.
