Fun fact about my hometown: Tulsa, Oklahoma. Tulsa Race Riot.

The Tulsa Race Riot was a large-scale racially motivated conflict on May 31 and June 1, 1921, in which whites attacked the black community of Tulsa, Oklahoma. It resulted in the Greenwood District, also known as 'the Black Wall Street' and the wealthiest African-American community in the United States, being burned to the ground. During the 16 hours of the assault, over 800 people were admitted to local hospitals with injuries, and more than 6,000 Greenwood residents were arrested and detained at three local facilities. An estimated 10,000 blacks were left homeless, and 35 city blocks composed of 1,256 residences were destroyed by fire. The official count of the dead by the Oklahoma Department of Vital Statistics was 39, but other estimates of black fatalities have been up to about 300.

Another fun fact, I lived in a small farming community outside of Tulsa and my sophomore-junior year in high school we had a "race riot" occur between black students and white supremacist rednecks. The rednecks went to several black kids houses with nooses, shotguns, and molotovs, threatening the kids to fight. There were a few fist fights outside of school, broken windows, and one pick axe to a car trunk, but that was the height of the fighting. But we had extra state troopers at the school and two ATF agents. It was a dramatic time at school.

TL;DR: Oklahoma is probably the most racist state in the union.
