I'm not sure of the kindest way to put this. Anyone can do what Aaron did. Each moment is a choice. Externalizing that kind of heroism is disempowering. The main thing stopping people is a brutally enforced lack of hope. That is exactly what eventually stopped him. His legacy has been built on, the work is nowhere near complete, and there is so much room for each and every one of us to continue making impactful contributions. He made reddit, we're on lemmy, who knows what's next? It's only with time that these actions seem larger than life. In the moment, to follow your morality is all that's necessary to keep moving towards a better world.
