If Americans had any self-respect Trump would would not be a candidate for the office of President of the United States. His rhetoric denigrates not only the institution of the President of the United States but the nation itself. If Americans weren't a nation of fools and fanatics, wise women and men would not need to remark upon their folly. 
America is a disreputable nation because it mollycoddles and promotes contemptible cretins. It would be difficult for anyone with even the slightest philosophical bend to refrain from commenting on the vulgarity that passes for patriotism in this increasingly smallish, warped culture.
