Subject: Re: It's always good to hear...
why the fuck is Donny always so angry?

Media. Specifically, Faux Noise, Alex Jones, OANN, and many more. They project anger, and publish stories designed to elicit anger (either through exaggeration or actual lies like PizzaGate). The RW media -especially- stokes that anger deliberately. Some LW outlets do, also, but not nearly as blatantly (or, frankly, not nearly as well).
