The question is, of course, what are the root causes of this decay of marriage in our country. In light of the intense debate elsewhere about the pros and cons of legalizing same-sex marriage it must be observed that there is as yet no definitive scientific evidence to suggest that the long campaign for the legalization of same-sex marriage contributed to these harmful trends. However, there are good reasons to believe that the decline in Dutch marriage may be connected to the successful public campaign for the opening of marriage to same-sex couples in the Netherlands. After all, supporters of same-sex marriage argued forcefully in favor of the (legal and social) separation of marriage from parenting. In parliament, advocates and opponents alike agreed that same-sex marriage would pave the way to greater acceptance of alternative forms of cohabitation.
In our judgment, it is difficult to imagine that a lengthy, highly visible, and ultimately successful campaign to persuade Dutch citizens that marriage is not connected to parenthood and that marriage and cohabitation are equally valid ‘lifestyle choices’ has not had serious social consequences. There are undoubtedly other factors that have contributed to the decline of the institution of marriage in our country. Further scientific research is needed to establish the relative importance of all these factors. At the same time, we wish to note that enough evidence of marital decline already exists to raise serious concerns about the wisdom of the efforts to deconstruct marriage in its traditional form.
Of more immediate importance than the debate about causality is the question what we in our country can do in order to reverse this harmful development. We call upon politicians, academics, and opinion leaders to acknowledge the facts that marriage in the Netherlands is now an endangered institution and that the many children born out of wedlock are likely to suffer the consequences of that development. A national debate about how we might strengthen marriage is now clearly in order.
