In case you required further proof

From the Gates of Vienna blog: Bostom’s book amply documents the systematic and destructive character of Islamic jihad, refuting the much-repeated argument that jihad is a “rich” concept that has many meanings and that jihad first of all signifies “inner struggle.” Jihad is first of all war, bloodshed, subjugation, and expansion of the faith by violence. The book implicitly devastates the fashionable but uninformed opinion that all religions are elaborations of the Golden Rule. Jihad is everything the Golden Rule is not.
