If your "default" reading of any sociopolitical proposal is to assume it is an absolutist desire and not one more nuanced or practical under the hood, you have a wrong default.
"Defund the police" meaning "zero funds for the police" or "no police exist". "Anti-work" meaning "against all work" or "work" meaning "general expenditure of productive effort" or something.
You can look a little bit more into any slogan or label and see more of what it entails. Hell, some people might want to abolish police entirely or have everyone laze around in utopian bliss while not starving. Feel free to disagree with the former and see if the latter have any plan to not starve or if it's nonsense. I've generally taken each to mean "we should allocate public security and safety money differently" and "our current construct of the job as the sole driver of societal worth is bad".
So "default" to something more reasoned and nuanced and see if they are absolutist rather than the reverse. Pithy and descriptive tend to not go hand in hand so this applies often.
