This fallacy relies on applying a binary level reasonning on a non-binary level which leaves only the choice between the two extremes. It is close to the false dilemna fallacy.Some minds tend to consider only extremes (love/hate, good/evil, etc.) and forget about the possible middle positions which leads to numerous logical fallacies, this is known as Manicheism.The opposite of this fallacy is the middleground fallacy.

This fallacy relies on setting a “middle” position in a level that accepts only two binary positions (0 - 1) such as existence. Any position outside of (0-1) in a binary level is a logical error. This error can come from applying a part-whole level reasonning on a binary level. Some minds tend to consider the middle position as always being the right one (Golden mean or Middle Way) they are prone to this kind of fallacy. The opposite of this fallacy is the Manicheist fallacy.
