The reason why social conservatives have declared a “culture war” is because their faulty understanding of society is that it rests on an imaginary conception of the family as the moral and economic pillar of society, based on patriarchal values and structure, a model that existed for a brief period of time and was the exception, not the traditional family. In reality, family structures vary and change based on larger structural factors such as the economy, technology and cultural factors as well. But, having posited this faulty model as the one and only that works and is functional for society, any variation is perceived as a dysfunction and deviance from the norm, especially if such variations challenges patriarchal ideas and structures.
And yet, these structures change for a variety of reasons that do not mean decline of the Western civilization.
Case 1: divorce legislation is social progress, as sociologist François de Singly notes here. For him (and as research has shown), divorce does not mean disruption or decetering of the notion of coupling but it does mean a right to say no and a right to end bad relationships if they do not satisfy the partners (one should always remember that low-divorce countries are usually countries where women do not have access to divorce and if they do, are placed at a monumental socioeconomic disadvantage, along with the stigma attached, thanks to religious conservatives). Therefore, it is not surprising that financially autonomous women are more likely to avail themselves of the opportunity. Progress! Divorce today is largely based on two individuals making decisions about their respective lives. There are heavy economic and financial consequences, but the real problem is the persistence inequalities between men and women that tend to be exacerbated by marriage. The more a couple has children, the more a man invests in his career, the more the wife’s career slows down and stalls. This is marriage costs mostly borne by women and that is largely hidden as long as the couple stays married and becomes highly visible when they get divorced.
