when i first clicked the article, i was all set to make a comment about how Extra Credits already talked about Hatred and Catharsis, just last week i believe, and that it was a lazy topic to choose.
but i was wrong. you had not only personal perspective on what catharsis and simulated violence can achieve, but also took a more laissez-faire approach to hatred's right to exist.
personally, i look forward to Hatred. because i think there is a DIFFERENT kind of catharsis in it: a macroscale catharsis. what i mean is that, looking at your examples, you cite small irritations of modern life: self absorbed passers-by, traffic jams, each representing it's own world, it's own context-less issue that you can that blow up and feel better.
but for some people (myself included) over time, you don't see these problems as individual problems, you see them as part of a greater fucked-up whole. you don't see a traffic jam, you see a world of shallow people driving cars they cant afford to jobs they hate to pay for shit they didn't want, but felt a compulsion to buy because of the state of capitalism and culture enforcing one another. you hate it all, and want it all to suffer.
now, i'm not gonna go on a rampage, but that doesn't mean there isn't a catharsis to be found in aimless violence, it's just not on the 1:1 scale your examples provide.
also, you sorta look like hawkeye in your picture.
EDIT: i did NOT mean to nearly directly quote fight club there...
