The lesson was this:
Sure we're all supposed to share resources and we all support Bernie Sanders taking from people and giving to others. But if there's a native group involved, then they have an absolute right to completely control any resource, for any reason. Even if the resource is infinitely valuable, and not sharing it will result in poverty and starvation for billions of people. The natives can't even be asked to talk about sharing it; their rights are supreme because they have the righteous skin color.
I consider Mauna Kea sacred ground that should be used only for telescopic exploration of the heavens. How can these heretics deny me my constitutional right of freedom of religion?
It doesn't matter. You don't have the righteous skin color, nor the righteous cultural origins. So, as far as the left is considered, you can fuck off.
