Chrisitanity always preached about non violence. Do you hear of any temples attacked by christians , inspite of all these attacks.
2. If you see Mahatma Gandhis teachings of non violence , and compare it to the teachings of Christ , you'll see the origins of India's Non Violent Origins.
If you're question is about the people who've served india ...
1. Anne besant 2. Mother Teresa 3. All those missionary run hospitals
Now you'll say that christians run institutions to convert people. Ask yourself , why would christian priests take care of aids patients , who are going to die in a few weeks. And after their death , why are they cremated according to their respective religions????
