Dating is a form of courtship. Courtship is the courter’s act of seeking the intent to marry from the courted. Therefore any dating which is not directed towards marriage is fraud, at best. Therefore any dating before an appropriate age to marry (whatever age that is) is fraud, at best.
So, what I want to know is: How many of those who say women should graduate college before they marry, or say women should reach the perfect mean age of marriage before they marry, forbid dating before that moment?
