You are exactly right. You do not practice non-violence with thugs. China deals with thugs outside its borders, inside it flushes them out. And so does all developed countries in the world. Our efforts in day to day life should take us more towards integrating modernity, money, matters and equality. And to do so, we have to keep on pursuing science, technology, art, architecture, research, development, sports, medicine, creativity and communication and yet guard and attack when needed as this will go on.
