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?
