In the Aikido dojo where I now train the children’s class is taught “anti-bully” moves. Aikido is aimed at controlling and deflecting aggression while not (necessarily) harming the aggressor. The drawback is that it is time consuming to learn but young people can learn much faster than an old fart like me. It inspires self-confidence though. Nowadays everbody goes for the easy satisfaction of kicking someone in the face.
