The article strongly equates anger with a desire for revenge. That's a bit confusing to me - for me, anger is just an emotion that's not particularly linked to any plan. Heck, I can even be angry at myself, in which case revenge doesn't even make sense. I think anger is most closely associated for me with "painful reflection on something that happened to me that felt unjust".
As an aside, while being easily angered is not good, I also think it's equally bad ritually suppress anger, because (a) that takes a toll over time that you eventually won't be able to suppress and (b) if you don't provide "feedback" to whatever it is that's angering you, it will probably happen again.
