Blu Anon 

A loosely organized network of Democrat voters, politicians, and media personalities who spread left-wing conspiracy theories. Blu Anon adherents fervently believe that right-wing extremists are going to storm Capitol Hill any day now and "remove" lawmakers from office, hence the need for the deployment of thousands of National Guard stationed at the US Capitol.

Hey, did you see that brave Democrat sitting on the Capitol steps on March 5 to "send a message to Q Anon"?
"Uh, yeah, that was Blu Anon, yo."
