Truly, a great many human beings erroneously believe that, in order to achieve anything worthwhile, meaningful, of success and of positive-victory, including traits, aspects, actions and expressions of love, peace, harmony, goodness, kindness, modesty, justice, <living and helping others to live>, suddenly denotes that the human being must become an all <yes-man>, or a complete <all-positive>, needing to sing songs and dances of endless positivity and <good times>, saying <yes> to every request from friends, acquaintances, co-workers, colleagues, their self-help guru overlords, bosses, family, lovers and so forth, so that these feeble-minded <yes-man> human beings find acceptance from their peers or gain political influences or possible power schemes as they rise higher in their corporate ladders.
Modern day human beings (as of 2020) have suffered terribly in language deterioration, greatly thanks to mass propaganda, careless media influences and of course, purposeful dumbing down of the mass-consciousness to turn human beings into nothing more than puppets for belief-based, religious-based, political and populist machinations that amount to keeping human beings independently-thoughtless, irresponsible and overly dependent on these <powers that be>. And that is exactly the way it was designed - to keep the mass majority of terrestrial humanity stupid, confused, mollycoddled, victimized (which also includes aggressive victims, not just crybaby ones, as @Severus Zohar pointed out in #psychology).
When such human beings are exposed even to an inkling of light (truth) in regards to their self-capabilities and self-power, then these human beings are simply unable to comprehend, let alone process or utilize such knowledge because they've been drummed into believing they have no power, and that it all comes from the government, father-god, a prophet, a teacher, a tin god, the police force, the political party or ideology they dumbly idolize, the military, secret services and intelligences, and so on and so forth. Time and time again, human beings are stripped of their basic Creational-right as a Wesen (entity, being) of Creation to wield their own power and indeed, be the smith of their destiny.
Precisely because of this reason is why an absolute <no> and in no wise a <sarcastic no>, must be enforced and used. The human being must learn to develop boundaries, limitations, moderation, modesty, and learn when is necessary to <switch off>, when is it necessary to talk and when it is necessary to keep silent or when it is necessary to perform work and exercise or when it's necessary to rest and recover. Many-a-earth-human-beings, especially after discovering #true-reality-teachings, foolishly believe that everything is suddenly fixed; that somehow, everyone else will get it - that they will simply say <yes>, and that he/she must go out and <tell it over the mountain> like a <yes-man>, implementing their formerly-religious and belief based thinking and lack of positive-negative-harmonization in order to convert other human beings due to their obvious lack of fundamental understanding of #true-reality-teaching, respectively - the spiritual teaching, and, or, material as a whole, that is of the truth, of the spirit, of the life, of the <real reality> and the <absolute truth>.
However, a word must be mentioned in regards to this sub-culture of sarcasm because on one hand it can be considered humorous to a certain degree, on another hand, it is completely detrimental to proper communication and reception of information. It is often cowardly used to passively mask problems, issues, deep, psychological and psychical tumors etc. which only bubble to the surface now and then or erupt in an absolute explosion. Sarcasm is a perfect tool of propaganda to distort the true meaning of words and the value of them, but it must also be said that while this is negative, positive can always be formed from negative, and in the case with <sarcasm culture> which is no exception to this rule, it can be said that this can increase the abstract, intuitive, communicative and linguistical intelligence of the human being, but only if he/she has learned to identify the true meaning of what is being relayed to them passed the surface-level expressions which includes: the literal words being said, the facial expressions and so on. In this case, one will need to be able to identify the true intention and the why behind the words and what is being said, what isn't being said etc.
Nevertheless, this confusion and language deterioration causes miscommunication and misunderstanding even amongst peoples speaking the same tongue. Now this is an important factor to the topic at hand because many people haven't a clue how to properly say <no> and how to properly say <yes>. These words, along with many others, have been flipped in their meaning, contextualization and usage, and it has brought nothing but confusion and false-assumptions, wrong linguistic structures and the like. However, the idea of <wrong linguistic structure> is only a half-relativity, because on one hand, language should be paid heed to from its roots, why it has existed, where it came from, where it descended etc., but on the other hand, it cannot be held to so tightly as the pinnacle of linguistic and communicative utter perfection because all languages on earth, German included, have their flaws and the only w
