Signs for the recent protest in Charlottesville, Virginia promised to “Unite the Right.” That expression was directed at white nationalist groups that oppose the removal of a statue from a public park in the city. The statue is of General Robert E. Lee, who led Confederate forces in battle during the Civil War. After four years of fighting, Union forces defeated the Confederates. The white nationalist groups have different plans and goals. Here is a look at some of the terms used to describe some of those present at the protest. White supremacists believe the white race is better than other races. The Southern Poverty Law Center (SPLC) is a nonprofit civil rights group. It says white supremacy is a historically-based system of abuse and oppression of continents, nations and peoples of color by white people and nations of the European continent. The SPLC says the aim of the system is to protect and defend a system of wealth, power and rights.
