I'm not doing any such thing. It's a democratic principle that no electorate should be held hostage by a past version of itself. This doesn't mean that votes should just be straight-up ignored, which I never have proposed and never will propose. But it does mean that proposing a future referendum is entirely consistent with democratic principles.
The vote in 2016 went against me, it is true, but it is a principle of democracy that I can continue to argue my case in spite of that defeat, and in future maybe even argue my case in a second referendum. I've lost count of the number of times I've pointed out to you that a second referendum was even originally a part of the case for holding the first referendum from Leave supporters. See, for example, articles by David Davis on the matter in 2013 (I've linked to it before). Or there's this, from Dominic Cummings, of all people:
Interviewer: "In the event of a [Leave] vote do you think the government would seek to hold another referendum, on the terms of the deal?"
Cummings: "I think that it's a distinct possibility, yes... and we obviously wouldn't oppose that... I think there's a strong democratic case for it."

For a while, at least, there was broad consensus amongst prominent Leave supporters that a future referendum on the terms of the deal (with the clear assumption that rejecting the deal meant rejecting Brexit altogether), was not only democratic but also desirable.
So, no. I neither want to run roughshod over democracy, nor am I doing so. It's unfortunate that the debate has become so polarised that any opposition to leaving is labelled anti-democratic, but that is the present state of politics. It belongs in the same dustbin as the utterly unfair accusation that Leave voters are/were racist.
