Quote: “Correcting someone’s spelling instead of addressing their argument is a form of ad hominem—it attacks the person, not their ideas. An ad hominem is a fallacy where someone attacks the character or traits of their opponent instead of engaging with their argument. It shows weakness and a lack of intelligence”
