The totality of the circumstances...their bouncies, their tantrums, their lies, their threats, their behavior online and in the physical world. They absolutely can not stand not being in charge, and they're willing and ready to burn the world down if it means they get to rule over the ashes.
Nearly every word and every action they take or claim to take shows us this.
The problem they have with this is their lack of impulse control means that effectiveness of one übermench shouting "hold ...HOLD" in an attempt to focus the force of the filthy, mindless mob of rank and file Dim'Rats - and DUmp'Rats - is of strictly limited utility.
From our perspective, this makes it difficult to tell for a certainty whether "The Revolution" has actually begun, or if it's just another leftist scum being an asshole on the perimeter.
