I think the idea that a) people lack nuance now or b) that it’s simply social media’s fault is the exact same kind of lack of nuance that you seem to be objecting to.
Nothing I’ve seen suggests that mass media or mass propaganda contains less nuance now versus any other time. Propaganda of all forms (regardless of whether delivered by newspaper, radio, tv, or facebook) has always been a blunt instrument.
Exactly. We aren't capable of discussing shit online, which is unfortunately where the bulk of our culture's negative discourse is occurring. It's not the posts, even - it's the comment sections.
I don't care if someone shares propaganda, I care about the discussion that happens after they share it, in the comments. When was the last time on FB/IG that you saw someone share some propaganda (true or untrue, doesn't matter), and looked in the comments to find someone correct them, and then the two had a reasoned conversation wherein they traded perspectives and ultimately came to a healthy understanding of one another even if they disagreed?
Do you see that sort of conversation, or do you just see a shitload of people yelling at each other?
