Yeah, British people got played dirty. A lead of 3,78% is not a real mandate for such a strong move. There was so much propaganda out there - anyone remember the NHS bus? Does anyone remember how much Russian influence campaigns were going on even then? And how extreme the British media was?
Many residents of the UK were not allowed to vote, all EU citizens for example or younger people, and they are also massively affected. And now, 8 years on, many of the older voters have also died. So "well, you voted for this, get fucked by your own greedy elites" is not the best argument to solve this mess
