I usually complain about the usage of the word "toxic" but at least here it's well-defined by the article. Still unnecessary though.
Their finding is interesting though - that "online political discourse tends to be uncivil because the people who opt into such discourse are generally uncivil".
And that begs the question why. My hypothesis is that it has to do with stupidity: political discussion offers a safe space for the stupid*, and uncivil interactions usually have at least one side being stupid. Doubly true in Reddit because stupidity there is seen like a badge of honour.
*NOTE: when I say "the stupid" I am not talking about a well-defined group of people. I'm talking about a set of behaviours (assumptiveness, context illiteracy, a tendency to oversimplify things, wishful thinking, lack of logical "parsing" etc.). Everyone is "the stupid" once in a while, but some way more often than others.
It isn't exactly what you're asking for, but here's how I prepare those instant lamen packages when I don't have frozen broth:
So the "broth" is mostly the juice of the vegs and meat, soy sauce, vinegar and condiments. It isn't exactly flavourful, but good enough.
If I had to improve it I'd probably use a chicken bouillon (for any land meat) or powdered dashi (for fish lamen). And perhaps half of a package of flavourless gelatine, for texture. (Some people might use miso instead. My body does not handle it well so I don't even have it, but it's an option for you.)
Sometimes I also add half a sheet of nori, as kombu is hard to find where I live. Taste-wise it's good, but be aware that you'll get some "nori fragments" at the bottom, I don't mind but the texture isn't exactly great.
