Shekhar, You have not studied Islam. Neither have the people who are bombing studied Islam. Both of you are in Same condition, Ignorance. Since you are ignorant you feel that Islam is about Terrorism and all muslims are terrorists. Infact there is no place for terrorism in Islam. Dont you have any friends, classmates, neigbours who are muslims?. What do you say about them?.
You must not vend your anger on an entire community just because of the deeds of handful view. You never know, money can lure anyone to do anything.
Learn, read, evaluate, look from the neutral stand point. Try finding the truth. You will be shocked.
