Marriage is vital as a framework within which children can be brought up by a man and woman. Not all marriages, of course, involve child-raising. And there are also, for that matter, same-sex couples already raising children. But the reality is that marriages tend towards child-raising and same-sex partnerships do not. I am conscious of this when considering my own circle of friends, quite a few of whom have recently married or will soon do so in the future. Many, if not most or all of them, will raise children. If, however, I or gay friends form civil partnerships, those are much more unlikely to involve raising children. So the question that matters is this: Why should a gay relationship be treated the same way as a marriage, despite this fundamental difference? A wealth of research demonstrates the marriage of a man and a woman provides children with the best life outcomes, that children raised in marriages that stay together do best across a whole range of measures. This is certainly not to cast aspersions on other families, but it does underscore the importance of marriage as an institution. This is why the demand for gay marriage goes doubly wrong. It is not a demand for marriage to be extended to gay people – it is a demand for marriage to be redefined. The understanding of marriage as an institution that exists and is supported for the sake of strong families changes to an understanding of marriage as merely the end-point of romance. If gay couples are considered equally eligible for marriage, even though gay relationships do not tend towards child-raising and cannot by definition give a child a mother and a father, the crucial understanding of what marriage is actually mainly for has been discarded. What that amounts to is the kind of marriage that puts adults before children. That, in my opinion, is ultimately selfish, and far too high a price to pay simply for the token gesture of treating opposite-sex relationships and same-sex relationships identically. And it is a token gesture. Isn’t it common sense, after all, to treat different situations differently? To put it personally, I do not feel in the least bit discriminated against by the fact that I cannot marry someone of the same-sex. I understand and accept that there are good reasons for this.
