A false dilemma is presenting just two solutions to an issue as if they were the only possible ones, when in reality there are other alternatives that were left out on purpose.
The example that everyone has heard
"Either you're with me, or you're against me." The phrase seems to exhaust the possibilities, but it almost never does. Between totally supporting and totally opposing there is a whole territory of intermediate positions, agreeing in part, disagreeing in part, proposing an alternative, which the false dilemma simply erases from the map.
Why it's a fallacy, not just a simplification
Simplifying is not, in itself, a logical error. The false dilemma becomes a fallacy when simplification is used to force a choice, deliberately hiding the other options so that the person feels forced to choose between the two extremes presented. The world almost never has just two doors, and whoever offers two has already decided, in advance, which one they want to push you through.
Where does he appear
The false dilemma is common in polarized debates, where any nuanced position is forcibly translated to one side of a dispute. "If you don't completely agree with me, then you're on the opposite side." It's a way to end the conversation before it examines real alternatives.
How to defend yourself from him
The question that dismantles the false dilemma is straightforward: "are these really the only options?" The honest answer is almost always no, and naming the third way is enough to take the force out of the manufactured dilemma.
This fallacy often goes hand in hand with strawman fallacy, because both simplify reality to make victory easier. The defense against both is the same: examine the real argument, with all its nuances, before accepting the framework that has been offered.
