I get the parliamentary kerfuffle, but I kinda mean opposition against secession in general. As I understand it, it wouldn't so much be like giving Native Americans random swaths of land, but giving the people living on specific swaths of land (which might be mostly Native Americans) that land, and no more influence over how the rest of the land is governed. Sorta like allowing California to become its own country, I suppose - why would other Americans have a problem with that, if the Californians wanted that?
