I disagree.

If I said "I like Germany because it is comprised of the superior Germanic race" that would be nationalism, but under your definition it would be patriotism.

If you're saying that this is not within your definition, then I think your usage of "good" in your definition is question begging.

I think I can see where you’re coming from with that criticism, but if I’m right then my error was an insufficient example.

I would count “I like Elbonia because we have the best mud farmers in the world” as patriotism. It may be untrue (which is a separate issue), and it may be chosen post-hoc as the only way to stand out (ditto), but it doesn’t imply other nations are no good at farming mud.

I would count your quoted example as nationalism for the same reason I would describe "I like men’s football because it is comprised of the superior male race" as sexism, while I would say that “I like men’s football more than women’s because I sexually fantasise about men and not women”, isn’t.
