I find it interesting that 'non-Americans' like the Belgians or Dutch are, in your mind, entitled to be displeased with modern Americans about slavery, simply because they are not American. A very large number of Americans are descendants of Native Americans, or blacks. Possibly also 'whites' at the same time (though many of those 'whites' were later non-Anglo arrivals). So you are in the odd position of justifying anger by (say) Dutch people against Americans who are related to them, or to Italians who arrived in 1920, or hispanics or blacks or Native Americans. Because, don't you know, non-Americans have every reason to be displeased with modern Americans on account of things some Americans did a long time ago. But the Dutch (as one example among many), of course nobody of that nationality did anything back then.
