These videogames still trouble us even if the villains make up only a very small part of the game. Of course, we go door to door on Halloween, but our costumes never have violent themes. We are also careful to point out inappropriately violent themes and the harm that it causes. Our children have never wanted violent toys, since we have taught them from infancy that these are bad toys. However, on occasion when they receive a violent toy as a present, we have an agreement that the toy gets thrown away and the child gets to chose a non-violent toy of equal value.
Everyday life is full of opportunities to teach non-violence.
I was recently disappointed with a popular historical novel covering the history of Poland, which I got for my child to read from the library. A huge portion of the book dwelt on wars and battles even though these make up only a very small portion of Polish history, albeit the most tragic portion. And the stories glorified Polish fighters in both sagas of victory and defeat. Peaceful resistance and successful conversion of one's enemies, while very common in real life and much more important in Polish history than violent resistance, was almost totally overlooked. This was an opportunity to discuss the issue of how often successful non-violent efforts are glossed over in history books that excessively focus on wars and rulers who often have had little to do with the advance of the human race.
