"I'm rejecting it on the grounds that it is anecdotal evidence wrapped in personal and popular belief."

This is not grounds to make a judgement.

It is a judgement in itself.

Made on what grounds?

My original post was an idea that I had that I felt was worth floating to see what what kind of reaction it got from people.

No prior belief, either personal or influenced by popular culture was involved.

"Your anecdotes, and the anecdotes of the others here posting about people they know who are angry all the time, are not evidence of any condition, except a very human one: someone is isn't very happy with their life."

Let's say that some of the testimony here is reliable despite it's apparent anecdotal form.

How would you explain an irrational and compulsive desire to create an artificial state of anger, so as - perhaps - to benefit from the 'positive' effects eg sense of catharsis, power, superiority, or ultimately (and being involved with kids you'll understand the pull of this last one) attention.
