I can understand why some people would feel the "wishes of the people" are being thwarted by those who can't accept the result of the referendum.
However, I think the point is that the whole process of leaving the EU, the making of new "deals", the Irish issue, etc, etc, were not properly addressed and, in some cases, not addressed at all. Additionally, it was presented as an inevitability that we would secure a good deal with the EU because it would be in both parties' interests and the EU were desperate to establish some sort of trade deal with us.
As the months and years go by, there is more and more evidence that leaving is not the simple process that people like Liam Fox said it would be. There are major concerns about all sorts of issues, including shortages of food and medicine, shortages of labour, the effects on research and development when we are outside of the EU umbrella, the reliance on the US for trade deals and an associated decline in health and safety standards for food, the problems arising with Ireland and Scotland, etc. None of these issues had been properly discussed prior to the referendum - I think both the leave and the remain campaigns were ill thought out and badly presented, relying on people's gut instincts rather than on facts.
As for those who think we are in a strong position as a country to make all these magnificent deals with all these other nations who are straining at the leash to trade with us, I'm wondering where they've been living for the last few years. The situation in this country re health, education, justice, employment, industrial output, housing, etc, etc, is absolutely dire, this government having run all of them into the ground. There is nothing to demonstrate that we have in place a team of competent people who can make good decisions for the country. Virtually every infrastructure project has been mismanaged in terms of cost and benefit and every tightening of the purse strings has caused a decline in many people's physical and mental health and all sorts of associated social problems that have had ongoing costly repercussions. Our government appears incapable of running this country effectively and to imagine that it has the ability to deal with momentous change effectively is very questionable.
