Don't fall for what passes for "truth" by the prescribers of false righteousness. They want peace at all costs. They are willing to overlook the crimes of abusers in order to keep things looking good on the surface. They want you to screw yourself by pretending someone didn't injure you, steal from you, slander you, etc. They demand you submit to bad treatment so they don't have to deal with anything as messy as your hurt or angry feelings at having been crapped on and screwed yet again. See what I'm saying? These people who condemn your negative feelings are demanding you put up with being raped. They are demanding your silence. In fact, in a real sense, they are piling on with the narcissist. They don't want to be inconvenienced by your justifiable reactions to evil deeds done to you or yours. Do not give moral weight to the opinions of someone who is only studying their own convenience and therefore willing to subvert justice in the name of a false peace or truce with evil.
Give up your quest to find peace at the cost of honesty. Be honest with yourself about what you feel. Attempts to lessen the guilt of the guilty is an illegitimate way to cope with your negative reactions to them. Accept the truth that a decent person should be angry and outraged at perverted and evil behaviors. Evil people create themselves. They stand before God Himself with no excuses for their evil deeds. He will strip away all their excuses in the final judgment and they will be forced to bear the full guilt for their choices. We should quit trying to be better than God Himself.
