So people should only live in lands where their ancestors are from?
Be native or be nothing?
That doesn't sound terrible.
European immigrants from all over would all have to return to Europe.
Too bad colonizers don't know how to do that.
I personally think people should be allowed to live anywhere and roam anywhere, as long as they don't colonize or commit genocide or try to take over the land in any way.
Basically:
"Mi casa es su casa" as long as you know it's been mi casa for thousands and thousands of years... And you are a guest.
