Social media users are perfectly aware that they’re ensconced in a bubble, and prefer it that way. It is a wilful ignorance. Conflicting perspectives, regardless of their substance, are flatly rejected or simply blocked. Self-affirmation is the objective. And in a climate of socioeconomic disenfranchisement and political disaffection, that participation imparts a measure of agency. This is the much vaunted democratising affordance of social media, and a cruel irony.
