I don't understand why it's even a matter of debate. It's obviously stupid to say "well we should just take hundreds of millions of people and just move them somewhere else". It's not gonna help anyone either and I really don't think many native people really want that anyways. It's a non issue, no one half normal thinks it is something that could ever be done any more or that it is even desirable, it's never ever gonna happen so why even have a heated conversation about it? You can't fix society just by moral aphorisms.
