Definition
An obstructionist is someone who deliberately delays or blocks progress, often through procedural tactics or refusal to cooperate. They hinder the normal course of events, usually in a political or organizational setting. Unlike someone who simply disagrees, an obstructionist actively works to prevent action. Think of them as the wrench thrown into the gears of a machine. They might use filibusters, endless amendments, or other stalling techniques. They frustrate others intentionally.
