I wouldn't say they're unrelated. If your father is a religious zealot who hates a certain group of people, and your primary social contact is hanging out with your friends drinking coffee, you may end up extremist or not. If your primary social contact is being saturated with hate speech 24/7 on social media, where you're punished for dissent, you will almost certainly turn into a zealot yourself. Yet this isn't even the whole problem, because almost no one you read on social media should even have access to a keyboard, let alone be allowed to bully peers into acquiescing to hate and violence. Facebook is responsible for genocide in Myanmar, and I don't think it's a huge stretch to say that its model (and social media's model in general) is responsible for the enormous wave of terrorist radicalization, school shootings, and violent antipathy toward civilized society that has overwhelmed the world since 2008.
