Ciro Santilli really likes his sense of humor, always going into "politically incorrect" areas, and often making fun of both dictatorships and the USA. He actually knows a bit about politics. Due to the nature of his humour, many of his earlier videos have been taken down from YouTube apparently, https://www.ssethtzeentach.com/videos mentions:
Ever since going full time, I'm usually very clean and stay out of trouble, but in the past a fair number of my videos were taken down.

Sseth has a certain vaporwave aesthetic, which Ciro also enjoys.
