So this is how outrage fatigue works, kind of.
Most lasers — actual devices that amplify light by stimulated emission of radiation — work by bouncing photons back and forth between mirrors through a lasing medium until — zot! — they slide through one partially-reflective mirror. I’ll let you look this shit up on Wikipedia if you so desire, as I’m too drunk to muster the giveafuck myself.
Software lasers are a mildly fanciful generalization of the concept: They get packets bouncing back and forth between mutually-antagonistic routers (or mail servers, or whatever) until one or both of the “mirrors” melts into more or less euphemistic slag. But the generalization is instructive.
A misery laser comes to happen when two or more people of similar political persuasion come together to bitch and moan about Things These Days. One person will bring up a topic that annoys their compatriots; the next will riff off of that topic to reinforce the notion that Things Are Going To Hell; the third will say “yes, and…” (and elaborate!), and then the malaise and frustration will reflect off of the side of the room and propagate back towards the first person.
Efforts to inject optimism into the system are, as you might expect, doomed to failure. You might as well shine a flashlight crosswise through a lasing medium.
Eventually, an optical laser will shoot coherent light off in one or the other direction of its major axis. A software laser will eventually fuck up one or the other mail server (or whatever the fuck services were having a spat). And eventually a misery laser will lead to an emotional breakdown, or perhaps (mostly) minor acts of physical violence.
This is why I don’t talk politics any more. And when people around me do, I fantasize about being on a motorcycle, on a twisty road, half a continent away. Continents are good for that; there’s usually a twisty road somewhere way the fuck far away.
