I am disappointed but not surprised that you seem to see only "bad shit" coming from brexit, no possibility of something good emerging. Yes, this has made clear divisions within society and there is atm 'no kind of coalition for change away from neoliberalism': which is why the task for socialists and anarchists, among others, is to work towards exploiting the situation to fight for positive change. It's not going to be handed out on a plate, you know.
I suspect some people would far rather eveything go to shit just so they can prove how right they were
