the world is roughly 100000% less violent than it used to be, and the violent crime rate has not increased much in the past 5-10 years. this is a total lie.
This isn't a lie, but it's also more nuanced than this. The world has been seeing a massive decrease in poverty. At the same time, only something like 4.6 billion people have internet.
I'm not saying that social media causes a flood of violence, I'm just saying that there are violent social contagions that should be addressed. Think of ISIS's social media campaigns for recruitment.
