You can spout as much b***ks as you want about how stupid leave voters are but you are wrong. There is a clear, easily explained reason why Leave won that you are too stupid to admit. The Leave vote offered hope that things would get better for people that have nothing whereas Remain told them that "this is the best it will get". Despite Leave now being seen as a Tory thing it was Remain that acted like Tories. They campaigned and voted to keep things the way they are because we already have it good (some would call this conservatism). Surely you can recognise the situation as being one that infuriates you when you are on the other side at a General Election.
Remian's arguments were all about what will be lost but they were trying to appeal to people that already have nothing to lose. People talking about the economy as a whole being better with immigration when the people that it directly affects via competition for jobs and stagnating wages only see the negatives. Remain utterly failed to offer any sort of positive reasoning for voting to stay or even any acknowledgment that the current situation could be improved. They tried to sell being an EU member as a utopia that we have already reached which for many is a kick in the nuts when they can see for themselves that their current situation is terrible.
It is not the Leave voters fault that they voted for hope or that Remain were too incompetent to offer any. It is not the Leave voters fault that the people that are responsible for carrying out Brexit have done a bad job of it. The responsibility falls on Parliament, and that includes MPs that wanted to Remain. After the result there should have been no more discussion on whether or not it was the right thing to do, it was decided by the people and that decision should have been respected. When people say it is remainers fault they don't mean you, the remain voter. You are irrelevant, you have no say in any decision. They mean the people in Parliament. Simple maths shows that in Parliament there was a clear majority of remain MPs. It was impossible for Leave to have a majority in anything they did and so it was remainers to blame for getting us into a position where a hard no deal brexit is the only option for getting Brexit at all. The government and the rest of Parliament are solely to blame for a multitude of things. The whole thing was a mess of arrogance where they assumed they'd win and then tried to wash their hands of it when they didn't but left no process in place for Leave to happen.
It was incompetence from the outset from Parliament. They should never have voted to approve the referendum to happen in the first place without an actionable plan to carry out if Leave won. You can blame leavers all you want but parliament voted for the referendum to happen (all except the SNP at least). They should not have voted for the referendum in the first place if they were unwilling to carry out the result. The way they have acted means we will never know what we could have achieved with Brexit because only the worst case scenario (and the one that remainers wanted the least) has been allowed to happen. Co-operation and a united front would have seen negotiations be very different and we may have managed something that was beneficial for us and the EU, if not perfect, but limited any downside. The necessity to be "right" appears to trump what is best.
In addition, since the result I have heard nothing but vitriol from the remainers who have developed some sort of self-appointed superiority complex and decided themselves as the arbiter of who is right and wrong. Suddenly everyone that thinks differently to them has been duped, or they are stupid, racist, selfish or a combination of all of the above. When people say that remainers have caused division and views to be entrenched then this is what they mean. Pre-referendum was fairly civil. Discussions were open and reasoned and there were many people that were unsure right up to the vote but since they ticked that box either way they have dug in and now they can see no benefit from the other side of the fence and it is now purely a defensive or aggressive position in any discussion.
