Since studies have documented the psychological damage in children associated with growing up in single-mother or divorced households, a society in in which nuclear families are the norm is a healthy society.
May I see some of those studies? I have never seen them.
Modern marriage is a joke. The idea of marriage in the West is completely misunderstood. It is not about "love" or "romance", but commitment. Commitment to raising healthy children! Love doesn't last but an arranged marriage in which both partners must commit or lose support of society, does last.
No, marriage is about love, not about children. You can have children without being married too.
