I was helping you prove your point
I think the hesitation really has nothing to do with the fact that it's political. I feel the hesitation is that DAK is all about EARTH and it's about creatures that lived, are living, or never were (mythical).
The dragon has been on the park logo since Day 1 and we never saw Beastly Kingdom come to fruition. That land would've been accepted because it's EARTHLY LORE and they are creatures that some believe really do exist, not just made up in a movie.
So, some see Avatar as the final nail in the Beastly Kingdom coffin...but in reality, when The Lost Continent opened with Islands of Adventure, the lid was shut.
