That's the one thing I absolutely loathe about Facebook. There's no constructive dialogue going on. Everyone is so full of themselves that any kind of argument derails pretty fast. And then there is the fact that the platform doesn't provide the structure for long conversations. After a couple of replies all text has the same indentation so it's hard to see who's responding to what comment. I've been online for twenty years, and I've never seen a environment more hostile to conversation than Facebook.
