Drivers, including Jimmie Johnson, Kyle Busch, Joey Logano and Ryan Blaney, all vowed to no longer work with helmet painter Jason Beam and his company, Beam Designs, after a series of social media posts took aim NASCAR’s recent moves against racial injustice. Bubba Wallace, NASCAR’s only current black driver, also described Beam as “garbage” while remarking that he had lost “all respect” for the painter.

“Nah homie, as person I’ve done business with in the past and ALWAYS respected the work you’ve done for ones in the industry,” Wallace tweeted to Beam on Thursday. “You made it clear of where you stand in today’s matter. All respect lost for ya dawg. #garbage”

The tweet included an image of an earlier tweet from Beam describing a newly unveiled Black Lives Matter themed paint job on Wallace’s car as “garbage,” along with a link to a later tweet that saw Beam thanking Wallace and NASCAR while claiming to “fully support the removal of the confederate flag.”

NASCAR instituted a full ban of the Confederate flag on Wednesday, after having earlier removed a policy that required people on the track to stand and place their hands over their hearts as the national anthem played. The decisions were both made amid widespread protests against racial injustice and police brutality.

“The presence of the Confederate flag at NASCAR events runs contrary to our commitment to providing a welcoming and inclusive environment for all fans, our competitors and our industry,” NASCAR wrote in a statement after the decision.

Beam was one of a small number of people associated with the stock car racing company to publicly speak out against the ban. Beam’s later tweet claiming to “fully support” the ban appears to have been deleted after Wallace issued his response.

“The Confederate Flag, North vs South in the Civil War, a war over separation of the Union, not slavery,” Beam wrote in one of several Tweets denouncing the ban. “But hey ignorance wins again, NASCAR you realize the North had slaves too, lol not just the South, you want to remove the American Flag as well, idiots.”

Other tweets by Beam bemoaned the “political spotlight of racism,” called Wednesday a “sad day” due to NASCAR’s announcement and questioned why the U.S. flag is still in use to “justify support for equality today.”

Beam also expressed admiration for NASCAR truck driver and owner Ray Ciccarelli, who had quickly announced his intent to retire due to the company’s recent decisions. A since-deleted tweet to Ciccarelli’s Facebook account described the moves as “political BS.” Beam praised Ciccarelli, saying he had stood up to “political propaganda.”

Shortly before Johnson announced he was cutting ties with Beam, the company’s Twitter account bragged about continuing to work on a helmet design for the seven-time Cup champion despite the backlash. After learning of the firing, the company tweeted that it had “been a great run.”

In the days leading up to the ban, the Black Lives Matter movement was also repeatedly derided in tweets by Beam, who insisted on using the phrase “all lives matter” instead.

Newsweek reached out to Beam Designs for comment. This article will be updated with any response.
