Gandhi would often refer to the Indian weakness in resisting as the main reason for the British rule, in opposition to the mere preponderance of force of the English people. In Swaraj in One Year, he states that, while his people are weak in spite of their number, the British are weak in numbers, and that´s why they need to resort to terrorist actions. The important thing is that both of them are weak, and the weakening that both nations experience is no good for either of them nor for the rest of the world.

You could either 1. discuss with the teacher(s) on how poorly he treats the classmates and try to find a way to get him to stop or You could try and talk to said bully about how is making the class feel with how he has been treating them
