Diamond and Silk are a social media duo famous for supporting Trump and claiming, without evidence, that Facebook "censored" them. Wonkette is a news, politics and culture website. Bianca DeLaRosa writes for it, and recently offered the opinion that Diamond and Silk were notable as "Black White Nationalists" due to their support of Trump's policies and their own ethnicity. Diamond and Silk threatened to sue Wonkette, it claims, over this opinion piece, and the cease-and-decist letter is amazing.
The consensus among lawyers on the internet appears to be that the "Diamond and Silk Legal Team" is not, technically, a lawyer.
