I do agree with Rokadia , ayub and pathan but not fully. As far as terrorism is concern, these are organisations of those people who are either unemployed or illiterate if we talk about mass. An illiterate person can be easily misguided and a man who is unemployed can be easily diverted to the wrong things. The literacy rate and employement rate is low in the muslim community but it does not mean that only muslims become terrorist. Any group which tries to disturb the communal harmony or peace shoulb be viewed as terrorist group, it may be SIMI, shiv sena or any political party. I am very much sure that very soon the condition will change.
