We live in a society where emotional expression is generally feared and avoided, yet anger is considered more socially appropriate than other (presumably weaker) emotions such as fear or shame. This makes the experience of anger far more tolerable for most people than what they are really feeling, so they funnel their fear, shame, regret, apprehension, guilt, embarrassment, sorrow or other emotions into anger. It's much easier to get angry and point the finger at someone else than it is to sit with a powerful negative emotion. Questioning the deeper emotion behind your anger is one of the most effective ways to eventually master it.
