Not In My BackYard: a person who opposes particular construction or projects in their community. Particularly prominent in
New York City.
Good NIMBYism: Jane Jacobs opposing the construction of the Lower Manhattan Expressway, which would have eviscerated the present-day
neighborhoods of SoHo, Greenwich Village, and TriBeCa; Jackie Kennedy saving Grand Central Terminal from demolition and replacement with an office tower.
Bad NIMBYism: Fighting the development of a nearby tall building because it might block your view; opposing a new subway line or water tunnel, which would benefit the city for
years to come, because of construction noise in your
neighborhood; opposing the expansion of the museum across the street because of minor inconveniences, even though it's the primary reason that your property is so valuable. I.E.: Being selfish
Iffy: People who fight LULUs, or Locally Unwanted Land Uses: developments or institutions that are needed, but that nobody wants near them, like homeless shelters or power plants.
