Another view of Romanticism

What struck me in the passage below was a view of Romanticism that I do not remember
seeing in any account of musical Romanticism. I include the context of the reference to Romanticism here in order to give you a sense of the impression it made on me when I first read it.

The New Yorker , June 14 & 21, 2004, p. 190:

“Thus it is not really the masses—who would presumably love to be liberated by the United States—but the fundamentalist leaders who are enraged. So, of course, are some of the Christian fundamentalists waiting for Armageddon on our own television screens. In fact, the war on modernity, often associated with the Jews, or the West, or the United States, goes back centuries. German Romanticism, which later curdled into a murderous ideology, began as a reaction to the French Enlightenment, whose ideals were promoted with armed force by Napoleon’s Grande Armée. Nineteenth-century Slavophiles in Russia resisted the modern ideas of the Westernizers and extolled the Russian soul. German Fascists in the nineteen-thirties denounced ‘Americanism.’ Japanese chauvinists in the forties embraced the idea that Japan was fighting a holy war against the wicked West.
Islamist extremists, it is plausible to conclude, have been drinking from that same poisoned well. Lewis rightly points out that their targets are the secular, corrupt, and oppressive governments in the Arab world, as well as the more enticing symbols of the West."
