A further point about this. You yourself live in a country that had a bloody revolution when one radical ideology ran amok, that time what one would later call liberalism, yet today, most of the ideas of the onetime radicals of the revolution have become reality. Incidentally, 19th century conservatives and centrists did use the example of Jacobite insanity and Napoleon to argue that Enlightement ideals can only lead to petty brutal dictatorships and chaos.
