Again, if they can procreate at that age, why ban them marrying with substantial parental and governmental input if they so choose to do so?
And picking 12 is a cop out, because the left seems to want to ban marriage before 18, yet are Ok with drugging and mutilating the kids at those ages.
What about 15? Again, biology allows people to procreate at that point, and discounting statutory rapes, which should be prosecuted, why should two 15 year olds who have a kid together be banned from marrying if the parents say OK and say a court agrees they are mature enough to do so?
