As you go though life, you will meet two types of people:

1) Those who seek to exploit you in unsustainable relationships

2) Those who negotiate with you, seeking mutually beneficial, sustainable relationships

The first are abusers, and enemies.
The second are allies.

To know who your abusers/enemies are, and who your allies are; DO NOT avoid conflict, for it is in conflict where you see who is who.

Strong men always define, and always protect their boundaries, when others cross them.

Fail at this, and people WILL exploit you.

When in conflict, allies will hear reason & evidence, honor Truth, and negotiate for a relationship that benefits you both.

Abusers will obfuscate Truth, and will try to manipulate you into abandoning your boundaries by invoking in you, feelings of fear, obligation, or guilt.

Objective Truth, and it's mutual acceptance, is what holds together a negotiated, functional, mutually beneficial relationship.

Abusers are interested in exploitation, NOT functional, mutually beneficial relationships.

Thus, the abuser sees Truth as an obstacle -- an enemy.

Abusers are never interested in Truth when they are abusing/exploiting you.

They will ALWAYS obfuscate the Truth when you defend your boundaries, so as to take more from you than they give you.

Abusers treat the Truth as their enemy.

Watch for this, and note who they are.
