The United States has always been a country of immigrants. The English-speaking Protestant Christians who founded the country, however, have not always welcomed other types of arrivals. The disdained have changed over time.

At one time, non-English-speaking northern Europeans were scorned. Then it was French Canadians, the famine Irish, Catholic Italians, anarchist Germans, fleeing Jews, Asian workers attacked by other immigrants, and Spanish-speaking Latin Americans.
In the big picture, the United States is in its second great wave of immigration since 1900. The first wave was primarily Europeans. It triggered restrictions on immigration in the 1920s. Loosened rules in the 1960s permitted the current wave, made up mostly of Latin Americans and Asians.
In 2015, Donald Trump said this of Mexican immigrants: "They’re bringing drugs. They’re bringing crime. They’re rapists. And some, I assume, are good people."
And this week Trump is alleged to have complained “Why are we having all these people from shithole countries come here?” during discussion of immigrants from El Salvador, Haiti and Africa.
