I think in some cases though there are systems that funnel people into places that seem designed to evoke engagement and often the engagement triggers outrage.

I wish Jack Dorsey at Twitter would take a look at the absolute shit-show that is "Trends for You" in the Explore section. It's nothing but the most outraged people trying to whip everyone into a frenzy. I try to resist going in there, but every once in a while can't help but be sucked in and almost always regret it.
