It is important to maintain as much mutual civic and cultural integration with our nearest neighbours as possible. Europe is still seen as hostile to British culture by many; when they have passed on or have lost some of the nationalistic fervour engendered by unbalanced and ill-informed journalism or extreme politicians, we shall need to reassure Europeans that we are not their enemy. That spirit - arising out of the chaos of WW2 - must not be submerged by the short-term rejection of continental values.
It is essential that the voter-base be as wide as possible; there are indications that the bigoted and ignorant, the easily-deceived and the less-educated swung the Brexit vote and the last General Election result. Foreign citizens, especially EU ones are usually well-qualified and well-educated. We must not lose their input.
I consider myself a European. Europe is our closest neighbour and we need to stay together for many reasons. I appreciate the contribution Europeans from many countries have made to our society. They deserve better treatment from our politicians. Solidarity should be our aim not division.
The country was hijacked by liars and vandals. People who say they know what they were voting for are liars / vandals / anarchists; many of the middle-ground misled leave voters would vote differently now. And the vast majority of those acutely affected (being EU residents in the UK, and UK residents in the EU) unable to vote, would surely have not voted to leave.
