I fear that as well.
I don't know if I posted this over the last couple of days, but I thought about saying it...
I am actually resigned now to the fact that the ONLY thing that even begins to start healing the huge divisions in society, is us leaving the EU. It's what the people narrowly voted for and we must deliver it. I know I've said the opposite over the past 3 years, but that was then and this is now. This shite is never going away until we enact the will of the people in the 2016 referendum.
Once we do that the angry Leavers will calm down, and us angry Remainers will have to suck it up, but we can reflect upon the fact that there was a referendum which we lost. And from that point we can start to rebuild bridges, trust and relationships. Until it's done, the country is hopelessly divided.
