The UK is a Union of countries. If you don't think that an event causing an increase in a desire for secession in one or more of these countries is damaging to that union, then I find your position impossible to understand. But fact I believe I've already defined your position in post #2743
I think what you mean is that the Little Englanders have had the opportunity to give vent to their xenophobia, and nothing else matters; the rest of us can **** off.
Now, the leave side won, in terms of the rules that applied to the referendum. Nobody denies that. What is being discussed is whether the referendum and its outcome were "good for the UK". Insofar as the UK is a Union of four countries, it was bad for the UK, because it has very clearly and evidently weakened the union.
It may be that you don't care about that, and you may be right - the UK may survive this crisis; but the outcome of the referendum, even if it does survive, is not good. If I contract a disease, but survive, does that mean the disease was "good for me"?
