So, to be clear, your position is the fictional land of Arendelle with its ice and Vikings and Norweigan mythology has nothing to do with Arendal, Norway with its ice and Vikings and Norweigan mythology? They are two completely different things in your mind and you can't see how Disney made the connection?
It's one thing to say that you don't want this theme to be a part of the World Showcase. Or to mourn the loss of Maelstrom. I can see opposing the change in lots of ways. But to say that Frozen has nothing to do with Norway is a bit of a stretch.
