No, this is a nonsense absolutist standpoint.
Britain held a referendum - one which probably shouldn’t have been held as it was, but it’s too late to hand-wring about that now. But the way in which the outcome is being executed is absolutey shameful and there are a number of things which could be done:
- the referendum outcome could be fulfilled by formally withdrawing from the EU while retaining most of the machinery involved - single market membership in particular.
- The UK government could make a clear and achievable proposal for what a post-Brexit relationship with the EU might look like. They had a stab at this, but the outcome failed to be either clear or achievable.
- The UK government could pledge to hold a second referendum once the end state of UK-EU relations is more clearly known. This fulfills any objections over democratic representation.
Any of these would be far better and far less cliff-edge than the current policy.
