> "Promoting less than maximally accurate beliefs is an act of sabotage. Don’t do it to anyone unless you’d also slash their tires"
Regardless of whether the first sentence is accurate (and indeed it certainly seems accurate), I believe the prescription given in the second sentence is not entirely accurate.
Slashing someone's tires is absolutely/always illegal (property damage, or whatever the term is for causing it) ... whereas sabotaging someone's beliefs is illegal iff the "someone" is a court of law or government official, or if the belief-being-sabotaged is about a living person such that a falsehood constitutes slander.
As such, sabotage of beliefs is possible in some cases where tire-slashing is not.
