Loving this story about successfully changing a conversation. It highlights the hidden power of language in how we think about the world. On the face of it, this conversation is about both saving a library and increasing taxes. It should be possible for people to hold both of those concepts in their head at the same time when discussing the topic. The reality though, is that by focusing on only one aspect of it (taxes) the other aspect (saving a library) can be occluded, even made invisible.
One of the key principles of Appreciative Inquiry is that the first question asked in any change is fateful; the question you ask, the issues you focus on and the stories you generate fundamentally shape the direction of conversation and the change that will follow.
Language and thought are more tightly coupled than we often think, and choosing a focus for conversation, and specific words to bring that conversation to life are far more important in change than we often give them credit for.
