Because you study it under family law does not mean it is the foundation of society....lawyers shouldn't discuss sociology studies...thye look foolish when they do.Marriage isn't a simple contract.
Marriage is the foundation for society. In law school, we study it in Family Law, not Contracts.
For example, if a poster named Tapeworm entered a contract for his monthly "wreck-tum" bleaching, would that be the foundation of society?
Let me answer that.
regardless, it is still a legal, binding contract as i stated. and the purview of the state as it always has been.
