A term used to describe militant individuals and organisations who use - or rather misuse - Islam (religion of Muslims) to further their political aims. They principally rely on terrorism and fear to obtain what they want and are helped by many governments who use these militants to instil fear into their own populace in order to justify an unnecessary reduction in civil liberties and the wanton disregard of privacy.
Most
neutrals agree that they do not represent Islam or Muslims in the least.
