fucking carebears destroying gaming interactions has been one of the worst memes
they're fighting basic human psychology. the biologically hardcoded roles that mammals assume while in play, showing dominance, abusing each other in a non-destructive way, showing competitiveness
people naturally take on roles as good guys and bad guys, same as kids playing cowboys and indians. If everyone has to play nice in a padded game where no one can grief anyone else, it just suppresses human behavior and makes it boring as fuck
