It is obvious that angry white men with immigrant roots want to make the USA a gated community and prevent the rightful/original landholders from reoccupying their stolen territories.
Indians are still kept on reservations.
I don't know what motivates angry white men to covet other people's land, but they have been doing this for centuries around the world with no thought to the harm they cause the natives.
In 1846, the U.S. illegally invaded Mexico and stole what is now the entire Western U.S. Need I mention Hawaii?
We have a sad history of colonialism and outright theft. And angry white immigrant Americans (exceptionalists) think that is just fine.
We are anti-immigration immigrants and far from the Christians we pretend to be.
