Bi-partisanship is bad enough in America, and in the world, thanks to the wedge issues Republicans jammed into their palms in the early 2000s, and along with that, the need for subtlety was dragged down to the ocean floor. Combined with written information's ultra-proliferation, and non-empathetic interaction rising at roughly the same time, we've arrived at an Internet with its own weird, sad twin-language.
The need for singular, specific words lessened, as there were fewer states of mind we were capable of properly conveying via the internet's dominant, limiting pathways. There was no need to mold words together into thoughtful exercises that may exercise a reader, too. The internet defined its own shorthand lexicon and repeated the words and phrases until they were sub-cultural memes, a streamlined text-form communication fit for the medium.
