I don't know about "most guilty", but when you have a group who first and foremost values intense self-critisism, they're going to be highly obnoxious on social media because of in-group signaling. For myself, I don't engage on this stuff on social media. But my mother gets all riled up arguing with her "republican jerks" and "trumps" on facebook. But in the end they all go out and drink too much and have a grand old time. It's a different mentality.
