I'm neither daft nor even pretending to be, but thanks all the same for the backhanded compliment, Pixie :P
As soon as Article 50 notification was given, the referendum result could never be ignored. Ignoring it would mean not having passed the necessary legislation, not giving notice, and not even bothering to enter into a period of negotiations. As to the claim that we must leave before deciding whether or not it's a good idea... it rather depends on your perspective of the available evidence, but there are certainly plenty of sound reasons to take seriously the idea that, in particular, a No Deal Brexit would be far more damaging than I am sure the country was hoping for. It doesn't make any sense to me to drive off the cliff and then decide if it was a good idea or not after you've crashed. I accept that you don't agree with this, because you don't accept that there's a cliff edge to start with, but it is completely mistaken to pretend that there's not even a case for seriously believing in one -- and as soon as you accept even the theoretical existence of such risks it becomes completely legitimate to argue in favour having a second referendum, or some other rethink, *before* leaving.
And, even if not, it is also utter nonsense to pretend that either a General Election leading to a party promising to repeal Article 50, or a further referendum with the same consequence, would be undemocratic. The only way the referendum in 2016 can be "ignored", then, is if the people, one way or another, choose to ignore it. And that is a choice that they are, or ought to be, free to make in a democracy.
