Consult your resentment. Its a revelatory emotion, for all its pathology. Its part of an evil triad: arrogance, deceit, and resentment. Nothing causes more harm than this underworld Trinity. But resentment always means one of two things. Either the resentful person is immature, in which case he or she should shut up, quit whining, and get on with it, or there is tyranny afootin which case the person subjugated has a moral obligation to speak up. Why? Because the consequence of remaining silent is worse. Of course, its easier in the moment to stay silent and avoid conflict. But in the long term, thats deadly. When you have something to say, silence is a lieand tyranny feeds on lies. When should you push back against oppression, despite the danger? When you start nursing secret fantasies of revenge; when your life is being poisoned and your imagination fills with the wish to devour and destroy.
