Hello Nydas, which parts they don't agree with? As in some view themselves as distinct from other Scots? The ethnogenesis of Scots isn't any less complicated than that of other peoples, it just happens to be a more recent one. As for the North American argument, it's the same thing with any other people. Italians in the US and Canada generally do not discrimante within their communities but back in the Old Country some people do care about Lombard or Norman heritage for example. That doesn't mean Italians don't exist.
