** One of the tactics used by [[WarHawk Gul Dukat]]. After the Klingons attacked, the new civilian government pressed for a diplomatic solution. This flew in the face of his pride, so he waged a one-ship war on the Klingons and then forged an alliance with [[TheEmpire the Dominion]]. He says the following to Major Kira:

* In the ''Literature/HorusHeresy'', former Death Guard Captain Garro is called out on making assumptions of this nature when he's blindsided by the betrayal of some White Scars.
-->'''Garro:''' The Khan's sons are loyal!\\
'''Rubio:''' Just as ''every'' son of Mortarion sided with Horus?!

In regards to RealLife examples, what may be considered as "a true/not a true (whatever)" often relies on personal interpretation which can result in heated arguments, so '''[[Administrivia/NoRealLifeExamplesPlease let's not go there]]'''.

** When Din and Boba Fett recruit Bo-Katan and Koska Reeves to rescue Grogu from Moff Gideon, Boba scoffs at Bo-Katan's aspiration to retake Mandalore, causing Bo-Katan to try to invoke this trope. Boba doesn't consider himself to be a Mandalorian anyway, but she still manages to hit his BerserkButton when she says he's a disgrace to his armor, and calls Jango Fett his [[CloningBlues "donor"]] instead of his father.

* If the action axiomatically [[note]]referring to base reasoning principles[[/note]] or logically disqualifies one from inclusion in the group, such as "No true bachelor is married" or "No true triangle has four sides." For example, "No right-handed person predominantly uses their left hand" is not fallacious because right-handed people are defined as those who predominantly use their right hand. Someone who is calling themselves "right-handed" but predominantly uses their left hand either is lying, trying to torture themselves, or doesn't understand the distinction between "right-handed" and "left-handed" people.[[labelnote:*]]Or is Phil Mickelson when talking about his sport of golf. He plays left-handed, and is widely known as [[RedBaron "Lefty"]] in golf circles, but does ''everything else'' right-handed.[[/labelnote]]

** ''LightNovel/FateZero'': Kiritsugu Emiya doesn't strive for the Root. Instead, he uses his Magecraft as a tool to be a mercenary and supplements it with technology like guns, bombs, night vision goggles, etc. Several characters like Kayneth El-Melloi angrily say he is not a real Magus.

** ''LightNovel/LordElMelloiIICaseFiles'': Several people say Waver Velvet is not a real Magus because he tends to use modern detective and forensic techniques instead of his rather weak Magecraft to solve magical mysteries.

* In the ''{{VideoGame/Borderlands 2}}'' DLC ''Tiny Tina's Assault on Dragon Keep'', Lilith is incredibly reluctant to let [[TestosteronePoisoning Mr. Torgue]] join in on their game of ''[[MagicAmpersand Bunkers & Badasses]]'' because [[GeekPhysiques he is a muscular guy, so she believes he's not a true geek]] and only wants to play because being geeky is "trendy" now. It's invoked again moments later when Tina asks him "Three Geeky Questions". Torgue gets the first two right, but the third has an UnexpectedlyObscureAnswer, and he doesn't know. Therefore, according to Lilith, Torgue isn't ''really'' into geek culture. After a great deal of InelegantBlubbering from Torgue, she reluctantly agrees to let him stay as a sidequest-giver. One wonders what her problem is, since she had no problem with Mordecai playing and he is very clearly not interested in the game or anything else geeky (of course, [[AtLeastIAdmitIt he doesn't try to pretend he is]], either).

* ''TabletopGame/DungeonsAndDragons'' writer and designer Monte Cook wasn't exactly discreet about [[CreatorsPet how much he liked Wizards]] and nor was he discreet about how much he hated Sorcerers, sabotaging the class' rules and abilities for years to keep Wizards top-tier. Another designer, Skip Williams, once went on record for openly saying that he despised the Sorcerer class and thought they were just discount Wizards. This despite the two classes playing in a very similar fashion.[[note]]For the uninitiated, both were {{Squishy Wizard}} type casters with similar spell lists, Wizards drew their magic power from years of magical study and so had a wider variety of spells which they collected in ther adventures and jotted down in their spellbooks; Sorcerers got their magic from some natural quirk, maybe exposure to raw magic in an accident or a draconic ancestor going way back, and had fewer spells with more uses and gained new ones every level.[[/note]]

** Ferengi Rule of Acquisition #18: A Ferengi without profit is no Ferengi at all; This is played heavily by Quark and Rom in different ways: Quark's relatively liberal attitude (he doesn't gouge his customers, and he gives his employees vacation time) earns him the ire of Liquidator Brunt for not being ruthless enough. Meanwhile Rom has no talent for or interest in profit whatsoever, and is generally considered to be a loser because of this (ironically he later becomes the financial leader of their whole race).

* In ''Webcomic/ElGoonishShive'', this is {{discussed}} in terms of the nebulous term "[[https://www.egscomics.com/egsnp/forreals-04 real fans]]".

* ''WebVideo/LinusTechTips'': In "[[https://youtu.be/mdFnY74dVNE?t=402 I Can't Believe Intel is Selling This.]]", Linus says Intel's Arc [=A370M=] GPU may be valuable as a video co-processor if you have a "real" GPU alongside it.

* In his early years, Ash Ketchum would often get hit with this in ''Anime/{{Pokemon}}'' whenever he used a Pokemon in a gym match that had a distinct type disadvantage against the leader he was facing. Ash usually brushed it off, finding it was his team's skills and not their type that mattered. Whether or not he was proven right or wrong often depended on each battle; for example, in Johto, his Chikorita was easily curbstomped by a flying type Pokemon (as grass types are weak against flying), but his next match saw Chikorita defeat a bug type (which is also strong against grass).

** From "hew-mon" standards, Quark is an appalling boss, but from Ferengi standards, he's quite benevolent. He gave food and medicine to Bajoran refugees at ''just above cost'' and tries to look out for his employees.
--->'''Quark''': I can reform! I'll start gouging the customers again! I'll revoke all my employees' vacation time!\\
'''Brunt:''' ...You gave them '''[[DiggingYourselfDeeper vacations]]'''?
*** In "The Siege of AR-357" Quark tries to disabuse his human-admiring nephew, Nog, by pointing out that Humans are nice if they are in comfort, but that if those creature comforts are taken away and a human is threatened, humans are just as, if not more, ruthless than a cold-blooded Klingon Warrior, while Ferengi do not act in such a manner and try to keep peace far longer than humans would. Later, when the camp is overrun by enemy troops, Quark kills one of the soldiers threatening him and a wounded Nog. Quark then looks at the gun and reacts in horror at the realization he grossly overestimated his willingness to compromise.

** The name "Qunari" itself is an example. Current and former followers of the Qun consider the term to apply only to members of the religion, but everyone else (including members of the same race) uses it as the name for the race. The same thing comes up with Elves; city elves don't think elves that assimilate into human culture are "real" elves, the wandering nomad tribes don't think city elves are "real" elves, and a remnant population of the original fallen Elf civilization doesn't consider either to be elves. The racially Elvish companion Sera who holds all "elfy" culture in disdain outright does this to ''herself'', insisting she's just "people".

* The Ninja/Gray Fox in ''VideoGame/MetalGearSolid'' proclaims to Solid Snake that a true warrior fights barehanded and only a fool would trust their life to a weapon. Fighting him barehanded will have him fight back in the same way and he becomes a lot easier to battle against. Trying to fight him with a gun will have him [[NoSell deflect your bullets iwth his sword]] and he attacks much more aggressively.

* ''TabletopGame/BattleTech'': The [[ProudWarriorRace Clans]] get into a lot of arguments about what the "true" way to be a Clanner is. As AsskickingEqualsAuthority, generally the "true" Clan way goes down to whomever is the best at beating up or killing anyone who argues with them.

* Drawing a line differentiating the traditional version of something against revisions, adaptations, or derivatives. The traditional version may still be recognized as either the original or the authentic version. This often comes up in matters of ethnic cuisine but also socially such as the terms "geek" or "nerd", the traditional definition as [[IntelligenceEqualsIsolation highly intelligent]] but [[NerdsAreVirgins unattractive males]] with NoSocialSkills. In recent decades, both terms were widely [[{{Hipster}} adapted by the mainstream ]] and [[NerdsAreSexy redefined to be a cool thing]]. However, an individual reserves the right for themselves to favor either the traditional or revisionist form.[[note]]Some individuals who grew up being ostracized by fitting the original definition would prefer not to be called geeks or nerds today. And many who regard themselves as nerds or geeks don't fit the original definition which, strictly speaking, generally did not include females.[[/note]]
