I don’t really believe there is such an animal as anger–it’s an evolved response to stimuli that might otherwise kill us if we pussyfoot (what a word) around too much. It seems to be the filter for the one feeling we as humans can’t seem to handle: being hurt.
There was a guy down the street from here that shot his ex-lover outside a bar with a freakin’ deer rifle. He felt hurt, I’m sure, but he couldn’t handle that so he turned it into anger and now he lives in prison. If we could just admit to such a simple thing that as humans we can feel hurt, maybe things like the Las Vegas shootings, or a women being shot down the street with a deer rifle could be avoided.
