A logical fallacy where one dismisses an argument by claiming the opponent is delusional, cognitively impaired, or using ableist slurs to describe their mental state. The fallacy lies in treating cognitive capacity as a refutation of claims, as if being confused or mistaken in some areas invalidates everything someone says. This fallacy is particularly toxic because it weaponizes genuine cognitive differences and disabilities, using them as cudgels to dismiss dissent. "You're delusional" becomes a way of saying "I don't need to engage with your points" while performing the appearance of having refuted them. It's argument by ableism, not by reason.
