  2. If thou art weak, chastise the strong.
  3. Covet thy neighbour's possessions.
  4. When vocabulary will not suffice, swear.
  5. Be wary and abusive to those who differ from thyself.
  6. If thou hast strong beliefs, proselytize.
  7. Be a hypocrite, for then thy true self is hidden.
  8. Speak, do not listen, for the world is thy stage.
  9. Ravage the Earth, for it is infinite in resource.

There's also a little-known 11th comandment:
