All of us do not get "stuck" there...only some of us. The ones who get "stuck" are the ones who have never learned that sometimes things aren't fair...sometimes you don't get what you hoped for...sometimes you can't see the forest for the trees..sometimes the thing you are angry about is entirely of your own making! Part of growing up is learning these things..such people simply haven't evolved yet..hopefully they will...some of us catch on right away..some of us are slow learners. :)

For some its easier , so then they don't have to communicate , me for one It's taken me years to understand what I'm angry about and pin pointing where the anger should be directed , in order for me to let it go ( spilled my guts on this one ) + 5

Anger is like an octopus with many extremities to pull you in and capture you. mature people learn to compartmentalize their anger, process it in a healthy manner, and move on. The problem is we are not all that healthy and we don't necessarily want to do the hard work requires to get healthy. Good question.

They don't know how to release it, and are too afraid to let it go.

It's been my experience that it's easier to get angry and blame someone else than it is to own up to your feelings and overcome them.

Angers exciting :)

Because I SAID SO!!!!! ARRRRRGGGGG

Usually anger is an emotion that actually is masking either fear, sadness, or guilt. It's much easier to show anger than to own up to these other emotions in public.

Basically it's about protecting perceived identity. We form ideas about who we are... images, concepts, beliefs. These ideas are sort of like a clog of debris in a drain -- the more tightly they're packed together, the more they stop the flow of life. A rigid and fixed identity is the sworn enemy of the change and impermanence of life. But a rigid identity provides the ILLUSION of a solid "self": a ME which can be clearly defined and persists over the changes life throws at us. So in our ignorance, we cling to this rigid identity and try to make it survive and prevail over all threats. This is called "ego". When the ego is threatened or hurt, it protects itself by lashing out or defending... just as a wounded dog might try to bite or scratch it's antagonist. However, ego is a funny sort of animal, because while a real dog will generally calm down when the threat is removed, the ego -- being an abstract concept itself -- continues to see a threat long after the actual incident is past! For example, if I believe that turtles are the way to salvation, and someone challenges that belief, I may become angry and lash out at them. But even after they've walked away, the mere THOUGHT that someone dares to challenge my belief "somewhere out there" continues on. The possibility that my belief is shakey is itself a permanent threat to my identity... I must invest continuing energy in defending that identity from even *imagined* threats. The core issue here is that this KIND of identity is inauthentic -- it isn't truly "who I am", rather it's specific mental forms (thoughts, beliefs, images) to which the mind has become attached in it's endless quest to answer the question "who am I?". Basically, in the absence of real understanding, we cling to whatever bits of apparently solid matter we can find floating through the river of experience. This mistaken identity continues forever -- there's no cure. But the more we understand true identity and false identity, the easier it becomes to extract ourselves from the false forms. That's what spiritual development is all about.

It's easier than dealing with the real issue. That might involve some introspection; might not like what we find . We choose to be angry.

Humans learn by copying living examples. Humans will continue getting easily stuck in anger until _you_ decide to stop presenting that example to others and instead give a better example. An easy and effective way of doing that, freeing yourself when you are stuck, is by doing the releasing fixed attention exercise http://avataracademy.nl/exercises/releasing-fixed-attention.html preferrably with an Avatar® master. If you truly want to explore how and why this works for you, do the Avatar course.
