Call them what you want; I call them NIMBY activists because that's what they are. - What they are doing is immoral, and unreasonable. - If they wish to influence the use of property, then they are morally obligated to purchase that property. - Nobody has a right to encumber the property of another so that they can use it to further their own enjoyment.
True, true. Of course, these developments often impose significant costs -- monetary and otherwise -- on others. As a result, those affected have every right to seek whatever encumbrances are necessary to minimize those costs.
