Well, this has been the story of America pretty much forever. Historically, I'm gonna guess that Native Americans would have thought the same thing when Europeans colonized. Must have felt even more foreign to them.
The correct term is "aboriginals"
I'm a native American but I am not an aboriginal
The Comanches (known for brutal tortures) almost made Apaches extinct
"Mohawk" meant "flesheater" because Mohawks were cannibals
American aboriginals were some of the most vicious people who ever existed (as Declaration of Independence states)
The idea aboriginals were born to an allotted geography that all others had to respect is Marxist propaganda intended to discredit modern America
ALL countries are products of conquests and defeats - including wars between aboriginals
America got CA from a Mexico that was inchoate and ungovernable - it practically still is.
Past immigrants didn't come to US and get on WIC, SNAP, SS, emergency Medicaid and all sorts of other benefits America goes into debt to pay.
Current immies are an invasion force run by cartels and corrupt politicians who are ok with risking terror strikes and drugs that will kill 90k in a year.
Past immies respected America and wanted to be Americans
Corrupt politicians have taught them the America they broke into is bad and should be plundered as punishment
That's almost backfiring now and could be inmteresting
