I think I can see where you might feel that way about marriage, however, as others have noted there are other systems to get married by, I.E. Justice of the peace or some humanist/freethinkers can conduct cermonys, capts of ships...etc...I think the important thing is that you and your partner agree what each of you is bringing to the table and what your goals will be once you are married...Its about life time committment. Its about loving each other through thick and thin...its about having a recognized partnership. In my state for example...claiming to be the wife or spouse of someone makes it legally so...common-law marriage...filing taxes together as a couple does the same...its the fact that you are presenting your self as married that makes you married...splitting up at that point actually could require a divorce even though you were never officially married...
Regarding the religious roots and nature of marriage, the Ancient Romans had three types of marriage, all equally legitimate. Two were religious, one of which was the fully-blown religious ritual. The third was a purely secular, legal ceremony, usually undertaken by the lower classes.
In current terms, then, there are secular alternatives, which recognise that changes in legal stature and obligations. These are well worth looking into as an alternative to the religious ceremony.
As for myself, by the way, I am planning on a religious ceremony, but an Asatran one, as my proposed partner is a Lokean.
it's when, as a couple, you get beef from the fascists/intolerants
and it happens during stressful times or argument
is when atheism comes up at all... the world, scocieties just woke up to the internet; when money is key
yeah, folks get crafty; some go white collar and rip up mid class families
