Opinions reflect our individual decisions about what we like and what we choose to believe in the absence of knowledge. An opinion is never right nor wrong, nor even true or false. The answer is different for each one of us. The danger comes when people insist their opinions are better because they are based on superior knowledge. Wars happen when people try to force other people to live by opinions they hold to be superior to what you or I may believe.
Tales are the spice of human communication.
The best kind of tales are lies told for fun and to entertain. A good novel or even a short story can make a lonely night an enjoyable experience or a long ride in an airplane bearable. Like all lies, tales can be dangerous, if we start to believe they are true. When we believe a tale is true, we make the tale a myth. Sometimes believing a myth can help us escape our fear of the dark or the future, but clever charlatans use our belief in myths to convince us to give up our freedom and follow the charlatans into misery, war, and slavery.
