I think I'm the opposite. Outrage upsets me - particularly the trollish type. I can very easily take it personally, even when it's not directed at me. Which is possibly even less healthy than seeking it out! Probably both approaches stem from a need to feel 'right'? Because being Right seems to offer safety? Joining together in outrage can be validating, but it can quickly slide into bullying too - as all the Fails have shown. Then again, outrage against actual injustice, if directed into action, is a way of making the world better ... so I guess the answer is to choose your battles wisely.
