Being afraid, a person is perceiving that someone or something is an enemy or threat. Yet it not actually true that the thing is a threat. The person is just giving it that meaning and is seeing that projected onto the situation.
Believing there is justification for being afraid, based on what the person is *showing* themselves, as a false interpretation of what’s happening, the person believes they are being attacked.
Fear entails denial, since it is a mechanism for denying the presence of guilt and for accusing others of sin in order to try to get rid of it. Because of this denial, the fearful person sees themselves as "not guilty" and the other person as "the sinner/enemy/attacker".
This sets up the scenario of seeing oneself as a victim under attack. Not seeing their own guilt, and viewing themselves as "innocently afraid", and disassociating from the sin that they’re projected onto others, the fearful person then sees a JUSTIFICATION for being angry.
They see themselves unfairly treated and attacked against their will. This is in spite of the fact that they are attacking themselves with false perception, showing themselves an image of their own sin held out in front of them, projected onto someones else.
Being innocent when attacked, if it were true, would make them completely justified in being angry at what *appears* to be mis-treatment by others, even though it is mis-treatment of ones-self by one’s own belief in sin.
You will notice that often when people are angry it is because they are afraid. You will also notice that if the situation seems to escalate fear, the person will quickly shift into anger, an increase in voice volume, an increase in defensiveness, projection and blame, and eventually an angry viciousness will emerge. They think they are angry, but they are afraid.
Sometimes, being willing to admit that you are not *really* angry, but that you are in fact afraid, is enough to completely collapse the anger in a mere moment. This means you are *recognizing* the illusion more accurately, acknowledging that there is fear, not anger. Of course, it would be even more helpful to acknowledge the belief in guilt, which is behind all fear.
