To paraphrase: When you're on the shit end side of a capitalist system, you don't have time to do anything by try not to starve to death.
Ok, yea, to an extent, but when you're on the shit side of the spectrum and have been for generations, people tend to get desperate and look to others who claim to have the answers. These white nationalists and neo-Nazis are claiming to have the answers and they are seeking out very desperate people. I've listened to them speak before, they are fast talkers, their hate is subtle at first, speaking mostly in innuendo and coded language until you think they aren't so terrible and maybe have a few good ideas. It's insidious.
They are having the info session the first day in a semi-private location in a park and charging a fee, then the next day they are holding a public demonstration. From what I gather they expect and maybe even desire a physical altercation, something to bring them wider attention.
