Wikipedia said:False equivalence is a logical fallacy in which an equivalence is drawn between two subjects based on flawed or false reasoning. This fallacy is categorized as a fallacy of inconsistency. Colloquially, a false equivalence is often called "comparing apples and oranges."
Moral equivalence is a term used in political arguments or debate. It is an informal fallacy. The phrase describes a kind of indirect proof, but the reasoning is flawed because it distorts issues. It draws comparisons between different things to make a point that one is just as bad as the other or just as good as the other.
The user of the term imagines a kind of independent position above or beyond the two contenders. The moral equivalence theory allows someone using the term to appear both objective and detached at the same time.
The general form of the context for the use of the trope is:
- The actions of A are morally equivalent to the actions of B, therefore A is just as good or bad as B, regardless of what the actual actions are.
- Doing X is morally equivalent to doing Y, therefore someone doing X is just as good or bad someone doing Y, regardless of what X and Y actually are.
The concept of moral equivalence is not a term of philosophy; rather, it is only a logical fallacy used in arguments.
