How people, such as those in authority or a higher position love to just frequently change the language or context surrounding a sensitive subject in a short span of time and make the opposing arguments against their ever-changing proclamations somehow seem incongruous in current time to avoid general consensus for questioning their narratives or constant disinformation. For instance, you can quote an official word, information, story, document, definition from the dictionary, whatever, that is still being applied today, "officially" or "scientifically" by what an official, politician, doctor, or scientist said weeks/months ago, one that is held in high regard, and then suddenly be called "crazy" ,or, a "liar" by the average cable news watcher (someone who also trusts the source you got your information from) when these officials or highly regarded institutions do some "slight" changing to the previous context or language surrounding the subject in question to invalidate what is currently being brought to the table, or for what they've previously said before as "solid or official information that the public needs to take seriously", so the arguments brought forward somehow lose their merit as some "conspiracy nonsense" just by having the public convinced that they either "never said such things", or, "there was a reason for why they said such things" (nothing to see here btw), because all that's needed to keep people from questioning anything, is to keep them convinced, that anything they've been told for what is "official and unquestionable" will always be true, despite it being a frequent ever-changing phenomena, even if they've just been lied to right in front of them, or by any forms of authority or "officials" who keep telling them something else quite frequency, so frequent, that it sometimes even goes unnoticed in a sentence when they start talking in these recent theatrical hearings you see on TV.
To make it simple, I'll just say this: I strongly dislike people like Dr. Fauci, Ted Cruz, Rand Paul, DeSantis, Trump, Biden, Harris, among others who lead their herds off the edge of the cliff into an oblivious hole of insanity, and make as though it is either their faults in the end, acting like they shouldn't have trusted them, despite that being their very jobs to these people, or that only one party is responsible, making the act even more deceptive and confusing for those already living in constant fear and hatred.
