If that is simple to you, then you really haven’t done any research into the subject. Would you call the native tribes of Oklahoma colonizers after they regained much of their land from the state? Of course not, because it’s not as simple as I’ve described it - imagine a non-native Oklahoman calling the Chickasaw colonizers because suddenly they are in the jurisdiction of that Nation? That’s what extremists sound like, using charged words that evoke emotions from other situations unlike the one described.
