Great real science from a political scientist! Erin Mayo-Adam does it like Jane Goodall and applies what she found to the Parkland kids:
Social movements can form in response to a series of traumatic episodes — if and when they build grass-roots coalitions among groups and organizations that represent a variety of minority communities and others affected by the events. That can happen when the groups construct a collective identity based on two elements: common opponents and a shared traumatic past.
