For long time in europe marriage was just an contract with no religious importance. The weddings as a religious christian ceremony started when the church wanted to gain more control over the lives of people. In fact in 1563 was when Catholic church declared that marriages aren't "official" unless a priest is present in the ceremony. And 1566, they defined marriage as "The conjugal union of man and woman, contracted between two qualified persons, which obliges them to live together throughout life."
Both of those were basically acts of an interest group redefining marriage despite what the majority of the people or the society had previously thought acceptable.
And that is just europe. So why are countries and societys blindly obeying the relatively new commands by these religious groups? We were doing fine for thousands of years without religious marriages. And really, this has been going on for less than 500 years and already you can see how corrupted and amoral society has become due to this definition of marriage. We have reality tv, Kardashians, WBC, people are using drugs, kids are listening to dubstep and have you seen what they try to pass off as a meal during airplane flights?!?!
I say we go back to the good old days of 14th century. You know, back when people still has some morals.
