Many, but certainly not all, Argentines hate Brazilians, and vice versa.
Many, but not all, Mexicans, hate Salvidorans, and vice versa.
Many, but not all of this country or province are at odds with other countries or provinces of their own country.
It's always been so and anyone who thinks it will all end is crazy.
"Bigotry" is one of the most overused and abused epithets in America today, but it is far behind "racist/racism," "fascist/fascism," "Nazi," and "greedy/rich." Leftists are the premier hurlers of bigotry and hypocrisy. They claim the Republicans are "rich" but they have Michael Bloomberg, Tom Steyer, George Soros, Ted Turner, John Kerry, Al Gore, Hollywood Ignorati, the Obamas, the Clintons, and Fake Newsies by the hundreds.
