Dilbert creator Scott Adams declined Bill Sienkiewicz's drawing challenge for charity, concluding a social media back-and-forth between the two comic artists.

Birds of Prey writer Gail Simone suggested the two have a draw-off after Sienkiewicz and Adams got into an argument over Adams' claims that his comic strip Dilbert was canceled for "being white." Sienkiewicz took Simone's idea one step further and said they should participate in the challenge to raise money for Black Lives Matter (BLM), LGBTQ+ and women's rights charities.

Adams refused to participate and wrote in a now-deleted tweet that "I wouldn't give to a violent, racist group like BLM, but more importantly not the least in interacting with you."

"So... the draw-off with Scott 'Dilbert' Adams apparently isn’t happening," Sienkiewicz wrote on Facebook.

"He made it pretty clear on Twitter this AM. He got no interest. Racist's gotta racist, Irredeemable bag of shit's gotta Irredeemable bag of shit."

"I shouldn't be surprised," Sienkiewicz continued. "To everyone who said ITYS, duly noted. Me and my silly 'olivey-branchy, bridgey-buildy, let’s have a dialog & transcend this divide' nonsense."
