I am Appreciating your curiosity about extremist. Your Question is really a billion Dollars. Extremist is there in every religion, Now Media is the king and Media is ruling the world so far information is concerned. If a 50 year old Muslim will marry a 15 year old girl it will be the Head line of the News Paper and also in news in flash for at least one week. But at the same time if a 50 year nun-Muslim old man will rape a 15 year girl it will be news brief for one day in Media. Above all we need to think what made Muslim became extremist. I am a Muslim and I am also an Extremist because I am Extremely Just I am Extremely Helpful to the needy irrespective of religion and all. And this extreme element I have learned from my Islam. As per my knowledge about Islam there is no evidence that insists Muslim to become Bad extremist. Our Government should think what is making a Muslim an Bad Extremist .Government Should eliminate that Cause . So that in coming year no Muslim can be a Extremist rather Banning the SIMI and similar kind of organization which is a temporary phenomenon.
