Everyone came from somewhere else, including Indians, that doesn’t make them immigrants.
America was founded by Brits, who moved to British land and then had a revolution and created the greatest nation that has ever been, not immigrants.
Immigration didn’t really start in America until about 1850, and then they started flooding in and changing us.
Today, legal and illegal makes no real difference except temporarily to the individual immigrant and their kids, an illegal from 1975 and a legal from 1975, have the same effect on our culture and the democrat party, the difference being that the legal immigrant gets to vote democrat sooner, than the illegal.
The Lakota Sioux say it started sooner...
