Pope Francis
Fratelli Tutti §44
Fratelli Tutti: On Fraternity and Social Friendship
44 Even as individuals maintain their comfortable consumerist isolation, they can choose a form of constant and febrile bonding that encourages remarkable hostility, insults, abuse, defamation and verbal violence destructive of others, and this with a lack of restraint that could not exist in physical contact without tearing us all apart. Social aggression has found unparalleled room for expansion through computers and mobile devices.
