Identification of Friend or Foe:
is a true foe just a person born without an ability to understand?
is a foe a person that has been damaged and no longer able to understand?
Is a foe a person that has been prevented from understanding?
Can someone still be a friend if they were born without an ability to comprehend and understand?
Can a friend be someone who has been damaged or prevented from understanding and comprehension?
Can any of these be reliably distinguished from a person who is truthfully retarded, vs a person that is just pretending to be stupid but still in a position to greatly effect the lives of many many innocent people????????
Anon is asking this because a useful answer and reliable method would unlock the situation holding humanity into a death spiral.
