The problem is not social media, it's that social media is you, a single person, interacting with a large system that presents to you a tapestry of complex opinions, videos and stories from a variety of groups to you, a person. You have your own internal system of views, opinions, values and personal feelings.

Being aware of this will naturally make you feel small and "weak", a kind of mental health "bigorexia" if you will. And in extreme cases, enough to consider the possibility that multiple personalities to be the greatest semi failed attempt to empathize with as many individual lives as possible.
