I have raised many children (8), and all of them are caring and kind.  It is because  a man and a woman raised them.  The complexity and the sensitivity of this job is incredibly grave.  There must be a natural order to all things regarding parenting;  the natural order is a parent's ally.  Deviating from this natural order is going to create very confused human beings;  the civilization does not need any more confusion than it already has.
