When one is on the opposing bank, there is a feeling of discomfort or uneasiness. But on the bridge, there's something for everyone to feel good about. If we want to change our campus culture, we need to forget about fighting the troll, build another bank to our river, find some pioneers to lead the effort, construct a bridge between the two banks, and give both the troll and the pioneers something to rave about. Attacking the culture with reactive and preventive policies and programs is not productive and solves a single problem rather than the problem. Reactive and preventive policies will always be needed for certain situations, but they're not the final answer by any means.
Peers listen to other peers better than they listen to anyone else.
And peers know what's best for each other because they can relate in a way that is more profound than the interaction they have with non-peers. Student leaders cannot do the work of changing a culture unless they have a ton of support from the university. No one can tell the troll what to do except himself. All we can do is everything possible to encourage the change while insuring there are some necessary reactive and preventive measures in place. The bridge is the keystone.
