Why bullies tend to become more aggressive when you show them you just want peace?

They want to make you angry, that is what they thrive on. Like a compensation for something in their life which is of no satisfaction in their life. When you what peace, that awakes negative emotions from the bullies subconscious signalling: "we do not like that behavior". This pattern need to change of course. I think it could begin with ones inner self-picture. Like are you a beggar or a king? One practice could be that you go to a crowded shopping mall and do a experiment. Imagine that you are a "nobody" and try to pass thru the crowd of people. You will most likely bump into a lot of people. Doing this again but with a mindset that you are a king or somebody important, but not arrogant! The change would probably much different ... Like the sea of the crowd is granting you a passage-way. Try it. Might need some practice though.
