A relationship would be good. Carl, they were started by Gavin McInnes and believe in Trump, Chauvanism, something something something (I forget). They like to fight at protests and were some of the most active at the Battle for Berkeley. they have initiation rights including a) getting bashed up until you can name 4 breakfast cereals, b) getting a tattoo of Proud Boys c) other things I can’t remember.
I think Gavin is distancing himself from them now. Based Stick Man now runs the LA chapter and they are pretty far Alt-Right from what I know.
