When you physically hurt me, it is violence. If you hurt me emotionally, it is violence. And if you hurt me spiritually, that is the worst violence, rank violence. When you convert somebody, you have to criticize the person's religion, his worship, his culture. All these hurt. When he converts, there is more hurt. He has to disown his parents, their wisdom and their culture, his ancestors and entire community. You isolate, uproot and emotionally unsettle him
