IRT "White settlers didn’t have green cards"
Not quite so.  More commonly, white settlers were invited, or allowed, into native lands by varieties of aboriginal natives.  When the white man knocked on native doors, they introduced themselves as to what and who they were.  Natives accepted them as such.  Even had Thanksgiving!!  The natives next reciprocated introducing themselves as to what and who they were.  BUT, the white man then said, "No, you're wrong.  Let me tell you exactly what and who you are."
