A collection of words and phrases that, although popular, are either inherently nonsensical, or carry connotations with their use that insinuate nonsensical ideas, legitimize bad behavior or villify innocent behavior.
"Try to be good"¶
To "try" means to make a choice that you think might cause a given result but is not guaranteed to. But a person necessarily has the final say in whether they make a more moral or a less moral choice. So when we use "try" or its synonyms in reference to moral behavior ("try not to sin", etc), we imply that the choice is not ultimately ours. Taken literally it denies the existence of free will, and while I don't think this phrase is a significant factor behind the apparently-growing self-aware-determinist movement, implications show up in other areas, such as the Christian practice of praying for God to give you virtue, and some Catholic speakers who outright say that you can't resist temptation without God's help. (I don't know the name of the film, but I heard this in my childhood in a short religious film about the Christian ideas in Lord of The Rings.)
It is as the great master Yoda (or more accurately the fool with this one wise saying) put it: Do or do not, there is no try. That's an excellent proverb when it's about willpower.
The problem with this term is that it excludes defending others. Taken literally, the implication is that it's okay to use violence in defense of yourself but not okay to use violence in defense of other innocents.
Of course, few or no one believes that, but I don't think it's accurate to say that the term isn't causing any harm because no one outright believes it. I've had an experience where people acted this way, after all. I don't think many people are bigoted enough to say the kid wouldn't have been justified to defend himself, but somehow other people defending him is seen as interfering with someone else's parenting or some crap.
Unfortunately there aren't any easy alternatives to this phrase. Sometimes I use phrases like "defending the innocent" but that's so much longer and doesn't make the same instinctive connection, because the phrase isn't in standard use. So even I end up talking about "self-defense" for convenience often.
"Harm", "hurt", "violence"¶
These words are used in such a way that a negative use ("nonviolent") implies something is "peaceful" behavior, yet a positive use carries a strong connotation of only referring to physical pain or damage and excluding other actions that aggress against another person's autonomy. For example, invading someone's bodily space, touching them without consent in non-injurious ways, intentionally slandering them, "playfully" interfering with their use of their belongings, refusing to leave them in peace when they're in their own territory minding their own business, lying to them or taking their freedom of movement; these things are often portrayed as merely "annoying" behavior and not grounds for "violent" retaliation.
Still, "violence" is useful as an ideograph against statists, who need the emotional manipulation to help them see through their indoctrination, especially for calling out the enforcement fallacy. But in general it does us a disservice that these words are so particularly - yet not strictly - associated with physical pain and damage.
Some alternatives that don't carry this propagandic connotation are "infringe" and "violate". They're not a perfect solution though, since they sound a bit too formal for some contexts.
This one is overpoweringly strong. Many people instantly dismiss something if it seems like a "conspiracy theory", no matter how rational it is. (Personal anecdote: when I first came up with the free will refutation of materialism and had the ensuing argument where I didn't shy from the implication that an entire field of science is wrong, one of the people I was with responded with "You're gonna grow up to be a consiracy theorist". Somehow, that refuted the argument, or something.)
It's pretty clear why this one exists; the state benefits from it. It's also plenty self-evident that there's nothing about conspiracy theories that makes them more likely to be false than any other type of theory.
If you're an "extremist", the natural question is "extreme about what?" Something good, bad, or neutral? Or at least, it should be.
Somehow, "extremist" is frequently used as if it means "terrorist", or something close ("Islamic extremists" in particular is commonly used as a synonym for "Islamic terrorists"). The reason this is a cultural thing is of course because of the Taboo of vanity, and we should strive to weaken this connotation by either avoiding the word or using it in positive ways. If anything, "extremist" should be a label to be proud of because it should mean caring a lot about something.
The perverse ideograph appears also with related words, for example "far-right".
"Judge, jury, and executioner"¶
This phrase is used to give the impression that an individual who thinks someone is guilty is wrong to act on the belief without the support of an established system of courts and police. It's senseless in principle because morality is independent of the decisions of such systems, and in practice the idea creates horrible incentive problems.
"Serve time", "penitentiary", "correctional facility"¶
Time spent in prison is not "serving" anyone; it is time during which one is prevented from making restitution or doing anything of value and forced to live off the resources of the innocent. Similarly, no correction is made; repentance is punished the most because criminals are denied the chance to labor in reparation. Imprisonment corrects nothing and serves no one.
"Rule of law"¶
Government is the antithesis of "the rule of law" because it is human beings determining what the laws are. Under a state, the law does not rule humans; humans rule the law.
Oh... that's what it means! It's all in the ambiguity of English "of"! The phrase was supposed to mean "the rule of law by humans"! If you read it that way, it's certainly not a myth!
