But some of the nonsense was evil, since it concealed great crimes. For example, teachers of children in the United States of America wrote this date on blackboards again and again, and asked the children to memorize it with pride and joy: 1492. The teachers told the children that this was when their continent was discovered by human beings. Actually, millions of human beings were already living full and imaginative lives on the continent in 1492. That was simply the year in which sea pirates began to cheat and rob and kill them.
