I think of two reasons why it appears as if only Muslims seem to fight in the name of Islam but members of other religions seem to fight in the names of other things than their religion.
I don’t think that the reason is the violent nature of Islam or Muslims at all. The first reason may be that the mainstream western media exaggerates the religious motives among militant Muslims but do not show the same care to emphasize such motives when they are among militant members of other religions. In a world where the USA, the contemporary vanguard of western imperialistic ambitions, targets the Muslim world, perhaps it is deemed more essential by some western circles of power to make Islam’s appeal to the masses less strong than any other religion’s. That may be why they are doing this to Islam and not other religions.
Another reason may be that neither in the conscience of the Christians and the Jews, who have been largely secularized, nor maybe in the conscience of members of other religions does religion occupy such a high position as Islam does in the conscience of Muslims. Therefore when a Muslim looks for justification of his acts, he looks at Islam because Islam represents the highest level of moral values for him or the Muslim society around him. But a Christian does not care to look at Christianity for justification and inspiration any more. He and the society around him have other and, to their mind, more rational and higher causes for war and violence than the Muslim, such as the spread of [the western understanding of] democracy, civilization and liberty to other parts of the world.
Just an opinion.
