i guess we are kinda hardwired as humans to react to perceived danger/threats. warm and fuzzy nice feelings seem harder to cultivate and take a lot of persistent effort. so it’s much easier to fall into this anger/hatewatching cycle than the other more compassionate/reasonable/warm and fuzzy side.
dunno, most of this comment is probably pop psych bs, but it feels right for my experience so i dunno.
fwiw, i hope your friends finds their way to something a little more peaceful one day.
