Nietzsche was not saying this was acceptable. He had no use for religion, nationalism or racism. Nature is the will to power. He believed humans would evolve to an even higher state--the overman.
Nietzsche would not have agreed with the present war and especially the present US administration.
Why do you support the US actions and propoganda and use Nietzsche??? I do not believe you have ever studied him at all.
As far as Islam, Nietzshe says in The Antichrist--
Hidden vengefulness, petty envy, became master! Everything wretched, intrinsically ailing, and invaded by bad feelings, the whole ghetto-world of the soul, was at once on top!--One needs but read any of the Christian agitators, for example, St. Augustine, in order to realize, in order to smell, what filthy fellows came to the top. It would be an error, however, to assume that there was any lack of understanding in the leaders of the Christian movement:--ah, but they were clever, clever to the point of holiness, these fathers of the church! What they lacked was something quite different. Nature neglected--perhaps forgot--to give them even the most modest endowment of respectable, of upright, of cleanly instincts. . . Between ourselves, they are not even men. . . . If Islam despises Christianity, it has a thousandfold right to do so: Islam at least assumes that it is dealing with men. . . .
And he also said--
Christianity destroyed for us the whole harvest of ancient civilization, and later it also destroyed for us the whole harvest of Mohammedan civilization. The wonderful culture of the Moors in Spain, which was fundamentally nearer to us and appealed more to our senses and tastes than that of Rome and Greece, was trampled down (--I do not say by what sort of feet--) Why? Because it had to thank noble and manly instincts for its origin--because it said yes to life, even to the rare and refined luxuriousness of Moorish life! . . .
And to close--
This eternal accusation against Christianity I shall write upon all walls, wherever walls are to be found--I have letters that even the blind will be able to see. . . . I call Christianity the one great curse, the one great intrinsic depravity, the one great instinct of revenge, for which no means are venomous enough, or secret, subterranean and small enough,--I call it the one immortal blemish upon the human race. . . .
