"There is a vast gulf of moral difference between animalistic and exploitative sex between underages kids, and a young teenage girl marrying. As people have mentioned before, and on this thread, in previous generations girls often married by their mid teens, usually to a young man a bit older than them. Some of our grandparents were these ages.
Marriage and illicit sex can't be compared."
You have consturcted a strawman to argue against. Your strawman is that Kansas prosecutes minors having underage sex and that is the purpose of the law. Since the law was passed in 1982, there must have been millions of prosecutions of consensual sex between two kids under 16. Why don't you find us one?
