> When Labour wins an election the entire Tory party doesn't switch over to their side of things.
Losers consent in the case you mentioned is that Labour accept the Tory government as legitimate. The difference is a referendum is supposed to be final (and it was indeed sold as so), but with an election the opposition will get elected again someday. The proper thing for Labour to do right now is push for the best deal they can to minimise what they believe is a bad decision. It should not be to try as hard as possible to do anything but Brexit.
> What law established this? This is particularly disingenuous given the explicitly non-binding nature of the first referendum.
No law established this, but given our unwritten constitution, can we really be certain that it's legal to ignore a referendum without court scrutiny (which has a divided opinion here btw)? The ballet paper literally said "The government will implement your decision" - I think it's fair to say if it has all the features/promises/legitimacy of a vote, it's a vote.
> You were perfectly happy to cite current opinion polls when you thought they supported your will of the people argument.
I was responding to your argument that a referendum is basically a poll (which I disagreed with anyway).
> A second referendum can absolutely be done with hindsight. "Gee, that didn't go well."
I'm not a fan of second referendum. I'm asking you honestly here, if it was remain won by 4%, and leavers were complaining for 3 years, would you call it legitimate to have another referendum so soon? Of course not, they'd be accused of being undemocratic and I believe they're right.
