if this is what the Indigenous would want with their land reclaimed, then it’s not up to you or me.

I was responding to you saying it necessarily means packing up and leaving. That is our point of contention. I agree with you that land back could lead to an ethnic cleansing in theory, though I agree also it's very unlikely. Perhaps I misunderstood you, but this is what you said that made me think you meant something else:

Motherfucker, landback means [...] you GO BACK too, no one should give a fuck about which gen. you’re currently a part of.

if this is what you’re worried about.

(a) I'm Canadian btw; US isn't the only colonial country. and (b) I'm not worried about it, no. It's a completely absurd and very improbable notion. Indeed, I often have to remind people who are worried about it that white genocide/ethnic cleansing/whatever is a total myth and conspiracy theory. So I'm shocked when I see on lemmy somebody talk about it as though it's a real thing.
