Argument to moderation
Argument to moderation (Latin: argumentum ad temperantiam, also known as middle ground, false compromise, gray fallacy and the golden mean fallacy) is a logical fallacy which asserts that given two positions there exists a compromise between them which must be correct.
An individual demonstrating the false compromise fallacy implies that the positions being considered represent extremes of a continuum of opinions, and that such extremes are always wrong, and the middle ground is always correct. This is not always the case. Sometimes only X or Y is acceptable, with no middle ground possible. Additionally, the middle ground fallacy allows any position to be invalidated, even those that have been reached by previous applications of the same method; all one must do is present yet another, radically opposed position, and the middle-ground compromise will be forced closer to that position. In politics, this is part of the basis behind Overton Window Theory.
