I think you have explained it close enough to the truth, The people that went out there representing everyone were the problem and continued to last day and still is the case. The withdrawal agreement was the last cock-up and the ordinary person has to deal with the consequences as usual They can blame everyone but Borris and his cronies accepted it and said it was a world beating deal or something to that effect.I have explained before but UK governments for decades pre the eu ref were all pro eu (remainers) the UK governments had a say in how the eec/eu changed they also had a veto, they obviously didn't make a very good job of it or why would more than half of those that voted want to leave if it was so great.
I blame the UK remainer governments for the leave vote, Major, Blair and Brown done as much or more for leave as nidge did. Never gave the UK people a direct say in how things evolved as Ireland did just ploughed on, well they reaped what they sowed.
I didn't vote for a vote BTW, in other words I didn't vote Tory when they promised a eu ref and had there been a option of remain but no more integration without asking the people (which is what they should have done before) I would probably have voted for that as it was I picked the least worst option
