Twitter has become a ground zero for racist messages aimed at Black folks, especially in recent months. A high school golf coach in Cambridge, Wisconsin just stepped down after his Twitter fingers left a trail of racist tweets.

Brent Nottestad, who resigned as coach at Cambridge High School Thursday, posted a slew of posts punctuated by prejudice about NASCAR driver Darrell Wallace Jr., who is Black, on Wednesday. Wallace is the first African-American full-time driver at NASCARโ€™s top level since 1971 and is the only Black face behind the wheel in the auto racing associationโ€™s circuits.

Four disturbing tweets, removed from Twitter, were posted as Nottestadโ€™s answer to Wallace having wrote that he is the one Black driver in NASCAR on the social media platform, the Cambridge News and Deerfield Independentreported.

โ€œThere is only 1 driver from an African American background at the top level of our sportโ€ฆ I am the 1. Youโ€™re not gonna stop hearing about โ€˜the black driverโ€™ for years. Embrace it, accept it and enjoy the journeyโ€ฆโ€ Wallace wrote on Wednesday.

Nottestadโ€™s response proved that he canโ€™t handle the truth.

โ€œHey @BubbaWallace. Please quit with, โ€˜Iโ€™m blackโ€™ bs. Youโ€™re terrible. There are 1423 more credible drivers to get that ride than you,โ€ Nottestad wrote.

The tweet set off so many alarms for having mentioned โ€œ1423,โ€ a number associated with the Alabama-based white supremacist group The Southern Brotherhood. Nottestad vehemently denied any awareness about the numberโ€™s significance in an expected move.

Another tweet referenced a photo of Wallace and a white NASCAR fan, with the caption, โ€œAlmost looks like going to the zoo.โ€ Other tweets by the now-axed coach said Wallace โ€œcanโ€™t drive himself out of an open wet paper bagโ€ and was a โ€œclown with zero ability.โ€ And another message alluded to Wallaceโ€™s deceased grandmother, who was a NASCAR fan.

Wallace, however, brilliantly condemned the hate served up like a platter by Nottestad.

โ€œWow, I feel truly sorry for your kids,โ€ the history-making driver wrote. โ€œAgainโ€ฆto have so much hate towards somebody youโ€™ve never met. Hope your kids grow up to be the exact opposite of a father you areโ€ฆโ€

Nottestad later admitted his โ€œhorrible mistake,โ€ he told The Associated Press. But no apology can erase the damage done by the now-fired coach, who proved that no amount of privilege gives anyone the right to express bigotry.

Officials at Cambridge High School have remained tight-lipped about the racist event except for releasing a brief statement that confirmed Nottestadโ€™s resignation. But Wallace not remaining silent about Nottestadโ€™s racist messages is what gives life to Black liberation.
