A lot of people refer to the anti box-store people as a vocal minority. However, it's not that they necessarily represent a minority viewpoint, they represent a minority of people who have really researched an issue and have concerns.
For most of my life I had no idea about the planning process behind city development. All I knew is that one day a new (insert name of store here) would show up. Until I became a newspaper reporter, I didn't realize that "regular people" had an opportunity to have input in the direction a city develops. In a particular city I wrote about, the Council dubbed the slow-growth people a "vocal minority" and ignored the so-called minority's concerns. Well, the "vocal minority" runs the City Council now, so maybe they weren't such a minority after all.
