I blame the internet. Back in the days before it, we had to learn to live with those around us, now you can just go out and find someone as equally stupid as yourself.
I call it the toaster fucker problem. Man wakes up in 1980, tells his friends “I want to fuck a toaster” Friends quite rightly berate and laugh at him, guy deals with it, maybe gets some therapy and goes on a bit better adjusted.
Guy in 2021 tells his friends that he wants to fuck a toaster, gets laughed at, immediately jumps on facebook and finds “Toaster Fucker Support group” where he reads that he’s actually oppressed and he needs to cut out everyone around him and should only listen to his fellow toaster fuckers.
Apply this analogy to literally any insular bubble, it applies as equally to /r/thedonald as it does to the emaciated Che Guevara larpers that cry thinking about ringing their favourite pizza place.
