Scott Alexander argues against broadening the definitions of words like 'lie' and 'abuse', as it dilutes their meaning and reduces their usefulness in identifying problematic behavior. Longer summary

Scott Alexander argues against broadening the definition of words like 'lie' and 'abuse' to include less severe actions. He contends that this dilutes the meaning of these terms, making them less useful for identifying genuinely problematic behavior. The post discusses how overly broad definitions can lead to everyone being labeled as liars or abusers, which removes the stigma and informational value of these terms. Scott also explains how this can be exploited by bad actors to unfairly stigmatize others. He extends this argument to other terms like 'disabled', 'queer', and 'autistic', suggesting that while some broadening of definitions can be useful, it's never right to define a term so broadly that it applies to everyone or no one.
