@kottke Nah, that's not it. It's simpler than than that. Their problems have been blamed on others. And therefore the solution is to attack others. As others aren't really the cause of the problems, attacking them doesn't solve them, so they have to attack harder. As the attacks grow, so does their frustration, because their problems only get worse.
This is why, with Fascism, the slippery slope fallacy ain't a fallacy.
I'm afraid it doesn't end in extinction burst, it ends in death camps.
@kottke One answer lies in an analogue from software development - it's called solutionising. Clients invariably come to you with solutions. "I need an app." Our job though is to start with *requirements*, so we have to walk them back. "What for?" "I'm a plumber, I need more costumers." Now starting from a requirement, we can reach different, more appropriate solutions - business listings, advertising, SEO, etc.
Attacking others is a "solution", but it was never derived from their requirements.
