I question the institution of marriage; period.
When divorces are skyrocketing, and so many people have to remain together because of their vows, although they are miserable,...I ask myself why the heck get married? They say we will all reach at least 80 years old. 100 isn't all that uncommon. Are we really made to stay with one person for 50 years or more? The institution of marriage has practically died out in France.
So, if children aren't a reason to marry,...then I don't get it. Is the divorce rate among gays the same as with hetros? Worse or less? That would be interesting.

Another thing; Wouldn't it be simpler to change the hospital rules about visiting rights,...then forcing people to marry just so they can get around those ridiculous rules.
