Clearly the only people not being represented are Greenlanders since Danes generally see Greenlanders as family to be respected and Greenlanders want to be gone, yet this hasn't happened.

This is basically a fight between government of Greenland, government of Denmark, and government of USA all acting generally against the wishes of their own populace. And somehow the dumbest of all options, the USA acquiring them, seems to be one of the more likely scenarios that actually ends up happening.
