That is not true.    I visited one of the pyramids and learned their history - 90% of the indigenous people were wiped out in the first century of "modernization".    Even today, they make up less than 20% of the population.

We all evolved from Africa.   Some migrated north, lost their tan, and enslaved those who did not.  Then some when to America, bringing their slaves with them.   Everyone black, white, asian, slavick, etc, has an immigrant to the Americas in their history.  Now that so many immigrants are born here, it is ignorant to tell someone to go back to their own country, unless you are indigenous. 

Illegal immigrants shouldn't have the rights of the country they are squatting in, but they do have human rights.    Trump forgets that - he's probably never squat in his life.  :/
