If this is true, I know a WHOLE lot of people who aren't actually married. You're trying to subsume a biological function-mating-into the social institution which has grown up around it-marriage. There are untold numbers of perfectly happy married couples without children either by choice or because one or the other of them is incapable of having children.

I expect all of those people would be fairly upset if you told them that their either lack of desire or lack of ability to procreate renders them not married.

The "study from Sacndinavia" argument is hilarious. Correlation does not equal causation and statistics are easily manipulated. If I had the link, I'd refer you to the Fark cliche which clearly shows that global warming is linked to a decrease in the number of pirates in the world.
