A logical fallacy
in which an argument
to prove one thing
s something else. If the argument is extremely long
, many people wouldn't notice
Example: "You should vote for J. Random Politician! Both George "W" Bush and Al Gore are beholden to large evil corporations for campaign contributions!" Maybe so, but you haven't proven why i should vote for J. Random, just that the other two suck.
To prove the conclusion irrelevant, show that the conclusion proved is not the one stated.
