Not that it particularly matters, but a "few people in Ireland" is perhaps an underestimate. It's the entire country at issue here. Northern Ireland voted to remain, and its interests, and the difficulty in reconciling those interests with the aims of Brexit, are the main reason that we are where we are now. Perhaps with a bit more understanding and less contempt people would have, if not voted to Remain after all, then certainly given more thought to the difficulties inherent in leaving.
I agree that a GE is unwelcome; but if not a GE, and if not an issue-specific vote, then what? You can't press on with a broken deal; Parliament will not allow a No Deal -- whether they are correct in this or not is clearly irrelevant -- and no other deal is forthcoming, at least without the UK making some serious changes in what it's trying to achieve and what it is prepared to give up for that; and nor can Parliament or any other body countenance unilaterally revoking Notification.
There has to be a resolution to the impasse, but that resolution can only come with explicit and unambiguous consent. Right now, there is none.
