The people who are keeping the myth of Abraham Lincoln alive are just afraid that if we knew the secret, they would actually have to face the cold, hard truth that he was just a creation of their imagination all this time, along with the alleged `slavery' associated with it. They are so afraid of this that they will kill in the name of Abraham Lincoln.
