Arrington de Dionysio is an "artist" who painted the murals that you see in Comet Ping Pong's ping pong area. (Source: https://m.youtube.com/watch?v=QAGLvLpmL2o&t=1s))

He is also a "musician" involved in a number of experimental neo-pagan projects. One of his projects is titled, "This Saxophone Kills Fascists": https://arringtondedionyso.bigcartel.com/artist/this-saxophone-kills-fascists

This kind of language used for the project may suggest a more solid ideological and social connection between the satanist pedo-network and Antifa.

You can actually contact him via his official website's contact page: https://arringtondedionyso.bigcartel.com/contact

This is his youtube: https://m.youtube.com/user/ArringtondeDionyso

He also co-founded a "music" festival that probably could be an extension of the pedo-network of affiliates: https://en.m.wikipedia.org/wiki/Olympia_Experimental_Music_Festival
