Disagreeing with someone’s perspective is one thing, but dismissing it is something else. People can disagree respectfully. Respectful disagreement involves listening carefully to other individuals in conversations, understanding their positions, and considering carefully the arguments that favor them (or that weigh against one’s own position) before replying. [Emphasis added] When a perspective is dismissed, however, it is rejected as so implausible—and perhaps so damaging—that it does not warrant a hearing. Dismissiveness is often accompanied with derision.Kevin T. Bauder
