Personally, I prefer to not be angry, as I find little pleasure in it, or use for it. There are some things that make me angry, and, I think, rightfully so, but for the most part, and I really mean most, well, it says, reconcile, but without giving approval to anger. In your anger do not sin, a sound warning, as sin crouches waiting inside of anger.
Wrongs that need righting, I find, are more quickly righted without anger. Some feel anger, and prize it as a possession. Other feelings too, I think.
Much love!
