Doctrinaire describes someone rigidly attached to a belief or doctrine, unwilling to consider alternative viewpoints. Think of someone stubbornly clinging to a political ideology, no matter what. It suggests inflexibility and a closed mind. It's not just believing in something; it's being dogmatic about it. Imagine a character in a movie who refuses to listen to reason because of their unwavering faith in a specific ideology—that's doctrinaire. It implies an unwillingness to adapt or compromise, even in the face of contradictory evidence.
