Hyperbolic internet rhetoric has resulted in the need to phrase everything as if you're a psych ward patient who cries when it rains because the sky is sad. If everything is a pitched battle between good and evil, anything less than screaming and beating your chest is weakness in the face of existential threats. The squeaky wheel gets the grease so everyone is squealing as loud as they can. Textual histrionics from people laying on their couch or sitting on the toilet staring at a little screen.

It's the same as typing "ROFL LMAO" when you actually just lightly exhaled through your nose.

It's infantile and distracts from "meaningful discourse". They're allowing themselves to be seriously psychologically manipulated (or are playacting along with it), but it just happens to be in a negative way this time.
