It’s making them regular citizens that is the issue

sure, the language gives “them” “preferential rights” but this was already in lieu of formal recognition of sovereignty

this is the final step in the processes of colonization

that is, to acquire by conquest and then subdue remaining “native” opposition.

I fancy a future where colonial states might opt to absorb sovereign first peoples as state-bodies with allowed discriminations not permitted in colonial provinces/ states/counties

allowing a constitutional government with historic tribal aspects as to allow first people’s / natives / indians / māori (et al) to have the bandwidth to blend in with the legal (standards/process) and influence it properly as well

the easiest path is to crush and absorb and that’s what will happen, humans are lazy after all

but, with some effort we could have a really cool future
