Haec Est Theoria Conspirationis Fallacy

A fallacy where someone dismisses arguments by labeling them "conspiracy theory." The label functions as automatic dismissal: if it's a conspiracy theory, it's false by definition. The fallacy lies in treating the label as refutation, ignoring that some conspiracy theories have been proven true and that the label is often used to suppress legitimate inquiry. It's a conversation-ender that uses stigma instead of argument.
