You don't think he should hold sole accountability?
What the fuck is wrong with you? He's the only one who went postal in general chat calling Mike a racist and suggesting white women prefer Arab men. Nobody else in LooseCannons incited him to do that.
Just because people were taken in by his campaign for leadership doesn't mean they should take responsibility for his actions afterwards.
All through history people have voted in leaders who've turned out to be absolute dipshits, or fucking maniacs. It's pretty likey they never knew that when they voted for them.
