@John Dayal That's because your reading is very limited (limited to those websites preaching hatred).
Terrorism is a state of mind. Heard of JVP in Srilanka (fashioned after, and trained by, the Khmer Rouge of Kampuchia)? Heard of the Japanese treatment of the Chinese and the Koreans in second world war?
Actually it is nothing to do with the religion or your faith. All hindus (in fact the majority) are not RSS or BJP. All brahmins (in fact the majority) are not Brahminists. In regard to fundamentalist inclinations, same is true of Christians and Muslims.
It is not your religion, or caste, or proffession, but your up-bringing, and sometimes your natural inclination that sets on the hate path and violence. Sometimes unfortunate ones fall into the wrong hands, and are indoctrinated with hatred.
But once you set yourself on that path you are never happy. you always want revenge, now, for all historical wrongs. You want to strike out blindly.. it is torture to your soul. I am watching Bhaskar Chatto and John dayal for sometimes, and feel very sad. If you go this way you will not have any peace of mind or happiness till the end of your life. You make life hell for others too..
