Before starting that argument, ask yourself one question:
Is it more important to be right, or to be married?
"While society is blessed by the contributions of virtuous citizens from all walks of life, research indicates that married people tend to be happier, healthier, and more productive, and they provide the best environment for raising children."
"Children raised by their own married biological parents experience less poverty, less drug and alcohol use and less crime and delinquency; they gain more education; they are more likely to marry; and they have better mental health compared with children from other family arrangements."
