None of us wants to tell a friend a truth like,
     1) he or she already has blood on his or her hands?
     2) that blood will become more personal and
          the conflict more intense?
     3) conflict will cause chaos and civilization collapse?
     4) most nations will fail?
     5) most survivors (5-10% of the present population)
          will be reduced to primitive lives?

We don't want to tell our listener a truth that:
     is harsh to the listener's ears.
     contains uncertainty
     lies outside the spatial and temporal perspective of
          the listener,
          the listener's peers,
          favorite expert, or
          religion.

We don't want to tell our listener a truth that:
          calls the listener's reality (faith and hope) pure fantasy.

Who wants to call the listener's attention to the unthinkable:
     "your system can survive if
          you kill your resource competitors.",

     that a perfect genocide is one that
          leaves most of the resources untapped and
     most infrastructure undamaged.
               See the "Eden proposition" for
                    a fictional presentation.

Who wants to deliver a message that,
     (when understood) might ,
          help people lose hope,
          trigger mass suicides (e.g., a Jones Town), or
          expose the utility of a global genocide.

Who wants to tell them,
    In "following the half truth they will kill their own children."
