With Us or Against Us in Live-Action TV series.
- The 100: In the Time Skip between seasons 4 and 5, Octavia becomes a brutal dictator over the people in the bunker, creating an almost cult-like atmosphere of death and destruction. The doctrine the bunker lives by is that "You are either Wonkru, or an enemy of Wonkru. Choose." The choice, of course, being death. It becomes almost a Madness Mantra of Wonkru, particularly for Octavia, and she sticks by it so closely that she's even willing to kill her brother for questioning her motives.
- Worse, she got this idea from Jaha, who contextualizes the All Crimes Are Equal atmosphere on the Ark as this trope. Resources were limited, so they made death their enemy. Anyone caught jeopardizing the population on the Ark, and putting them closer to death, would need to be removed from the population. Octavia's own mother was floated for this very reason, and nearly everyone in the 100 has lost a relative to this draconian rule. Unlike Wonkru, though, the Ark was run more democratically.
- In the Arrow episode "Vigilante," Vigilante says this almost word-for-word to Green Arrow, regarding Vigilante's war on crime. Green Arrow, seeing Vigilante as the crazy Knight Templar Vigilante Man he is, declares that he is against him. It's eventually revealed that Vigilante is a former Central City cop, who was shot in the head at the same moment as he was hit by the particle accelerator explosion. While the dark matter did grant him a Healing Factor, it may have also left him with some brain damage.
- Blake's 7. In "Star One", the Master Computer that runs the Terran Federation has been sabotaged, causing chaos across the galaxy. Supreme Commander Servalan uses this as a pretext to seize power, declaring that anyone who opposes her is part of the sabotage conspiracy. Ironically it was Servalan's self-centred scheming that lead to Star One being compromised in the first place.
- Played for Laughs on The Colbert Report, by being the basis of Stephen Colbert's life philosophy. "You're either with us or you're against us. It is either Coke or Pepsi. You're either gay or you fight it." Finally he states he divides the supermarket into "cheese" and "not cheese." He also tends to badger people, including guests, who do not fall into one of his two categories, with "Pick a side—we're at war."
- Parodied in a 2014 episode of The Daily Show, as Jon Stewart tries to talk about Israel's actions towards Palestine, only to be immediately shouted down by the Daily Show correspondents, who criticize him for being anti-Israel, one of whom even calls him a "self-loathing Jew." This leads Jon to mention that being critical of Israel's actions does not imply approving Hamas' actions. However, this leads to the correspondents shouting at him for ignoring the plight of the Palestinian people.
- Dominion: During the Extermination War, the higher angels declared neutrality, something that Michael respected. However, now that many of them have joined Gabriel, that agreement has been invalidated; Michael tells the higher angels living in secret in Vega to either stand with him, or leave the city.
- Game of Thrones:
- Queen Cersei Lannister tells her son Joffrey that "Everyone who isn't us is the enemy." This is all very well when House Lannister is the most powerful and wealthy family in the Seven Kingdoms, but after years of war drain their resources they make an alliance with House Tyrell. Cersei fails to understand the necessity for power-sharing, and her efforts to undermine the Tyrells instead of working with them cause disaster for everyone.
- Stannis Baratheon:
Stannis: The Iron Throne is mine. By right. All those that deny that are my foes. - Iron Fist (2017). Once he gains the power of the Iron Fist, Davos goes round killing members of the Triads. Joy Meachum argues that this will make him a Hero with Bad Publicity, so Davos approaches Mr. Yip, a local businessman who was being shaken down by the Triad gangs, and offers his protection free of charge. Yip however is afraid of taking sides in the conflict and refuses the offer, so Davos decides he's with the Triads and kills him, to the shock of his own gang.
- Napoléon: When Napoleon visits Fouché (the Minister of Police) to demand his support for Napoleon's coup on 18 brumaire, he states that Fouché must decide on the spot whether he's with him or against him. He also points out that he's now Fouché's only hope, since both the royalists and republicans will want to execute him for treason and conspiracy.
- Our Miss Brooks: Mr. Conklin's given Miss Brooks this ultimatum a couple times, in order to force her compliance with a dubious scheme of his. Usually, however, Mr. Conklin chooses to warn Miss Brooks that it's in his power to make her time at teaching at Madison High "either very pleasant or very miserable."
- In Power Rangers S.P.D., Emperor Grumm gave Piggy this ultimatum to ensure that he had his aid in his conquest of Earth. Even when Piggy said that he'd swear allegiance to him, Grumm still demanded he go into a pit of torture for a day to think it over.
- Sabrina the Teenage Witch: In the episode 'Inna Gadda Sabrina', when a time ball causes Westbridge to get stuck in the 1960s, Sabrina's friends and even her favourite teacher have a sit in to demand vegetarian options on the school menu. Valerie asks Sabrina to join them by stating "If you're not part of the solution, you're part of the problem."
- Star Trek: Deep Space Nine:
- Commander Kira tells this lesson to the Cardassians when they've started a rebellion. She's reminded in the same episode that Odo (her lover) used to be against the Bajorans while the Cardassians were occupying her planet.
- Kira to Odo: "We used to have a saying in the resistance, 'If you're not fighting them, you're helping them.'" Kira holds a very dichotomised view of "collaborators", particularly in the days immediately after the Cardassian Occupation, and one which is challenged on several occasions through the course of the series.
- In "The Darkness and the Light", members of her former terrorists cell were killed. Eventually she found that it was a Cardassian wounded in one of their bombings seeking revenge. He stated he'd been a civilian servant, not involved with the crimes against Bajorans, and worked in a building they bombed. Kira doesn't care- she considers them all guilty, as none of them should have been there on Bajor to begin with. Yes, there is a reason she admits to being a former terrorist...
- Commander Dolim gives this ultimatum on Star Trek: Enterprise when he announces that the Reptilian and Insectoid Xindi have taken control of the Earth-Shattering Kaboom weapon and are going to use it on Earth. The other Xindi refuse to cooperate with him, and civil war breaks out.
- Russel Hantz tried this phrase on Sandra during Survivor:Heroes Vs. Villains. Backfired spectacularly when Sandra immediately told him she was against him, something those on the Survivor Jury loved.
