Free-Floating Argument Fallacy

Free-Floating Argument Fallacy: Attempting to establish an absolute property of something (i.e. morality status) by comparison with something related, with no connection to an external point of reference. Free-floating arguments may sound convincing, but are meaningless on their own. They derive their perceived meaning from assumptions held by the speaker and (presumably) the audience about the things being compared. They are often stated in the form of an observation or question, with the argument only implied. They may have a very different or nonexistent meaning to someone holding different assumptions.
