Why do they say they are "politically correct"?

[first lines]

Dr. Kennebrew Beauregard: Hello, my fellow Americans. They say we may have lost the battle but we didn't lose the war. Yes, my friends, we are under attack. You may have read about this in your local newspapers or seen it on the evening news. That's right. We are living in an era marked by the spread of integration and miscegenation. The Brown decision. The Brown decision, forced upon us by the Jewish-controlled puppets on the U.S. Supreme Court, compelling white children to go to school with an inferior race, is the final nail in a coffin, is the final nail in a black coffin towards America becoming a mongrel nation. We had a great way of life. We had a great way of life. We had a great way of life. We had a great way of life until the Martin Luther Coons of this world and their army of Commies started their civil rights assault against our holy white Protestant values. Do you really want your precious white child going to school with Negroes? They're lying, dirty monkeys, stopping at nothing to gain their equality with white men. Rapists, murderers, craving the virgin white, is it "virgin pure"? Rapists, murderers, craving the virgin pure flesh of white women. They are super predators! And the Negro's insidious tactics, under the tutelage of high-ranking, blood-sucking Jews, using an army of outside northern black beast preda... agitators. God, watch this! God! Using an army of outside northern black beast agitators determined to overthrow the God-commanded and biblically inspired rule of the white race. It's an international Jewish conspiracy. May God bless us all.

Donald J. Trump: [referring to the Charlottesville riots] You had a group on one side that was bad, and you had a group on the other side that was also very violent. Not all of those people were neo-Nazis, believe me. Not all of those people were white supremacists. You also had people that were very fine people.

David Duke: Because I believe that today in Charlottesville, this is a first step toward making a realization of something that Trump alluded to earlier in the campaign, which is... This is the first step toward taking America back.

Charlottesville Riot Protestor #1: I had to jump out of the way. I almost got hit by the car my fucking self. There are people, bodies laying on the ground right now.

Charlottesville Riot Protestor #2: And there was a woman laying there, hardly breathing, and we ended up rolling her over, and she died.

Charlottesville Riot Protestor #1: This is my town! We did not want them motherfuckers here!
