I Am Why is a national, intergenerational organization catalyzing a power shift in which young women and gender expansive activists claim individual and collective power and use this power to advance their vision of justice. We use three strategies: 1) An authentic methodology, connecting young activists’ narratives to policy and practice; 2) Communications tools that clarify issues, reframe solutions and model shared power; and 3) Movement building through young activists’ direct engagement with systems we aim to change.
