A person who is pathologically contrary to everything that is said to him/her. Will argue black is white until they are blue...no green...no red in the face. Even if you agree with them they will rise up in opposition. Political life is the perfect arena for this kind of nonsense.
There will be a Great Disagreer who will restore balance to the earth. The Great Disagreer Will Disagree with anyone and always win the disagreement rather write or wrong. The Great Disagreer Will start a war and every person who disagrees with the Disagreer Will die. This will result in every person to be under the rule of the Great Disagreer.
