Donate if you can, and even if you can’t, spend some time this November educating yourself about the history of the very-much-still-alive tribe that sat down with the pilgrims, the continued history of colonization in America, and about the tribe/s whose land you are occupying.
I’d also recommend seeing if any of the tribes whose land your occupying has a language revitalization program of it’s own. More and more tribes are creating their own programs!
