Disagree.
Having a second referendum for the sole purpose of revoking our democratic decision to leave the EU would expose a critical flaw in the democratic process that would resonate with millions, particularly those who passionately or passively want to leave the EU. How could anyone have faith in referendums or democracy if it is proven to be impotent.
A no-deal scenario and a few weeks of chaos would be incomparably better for the country and its democracy than a second referendum, which would certainly cause irreparable long-term damage. Not that a no-deal is the preferred option, but it is still preferable to a second referendum.
I would suggest that a second referendum equally could be seen as ratifying the first referendum rather than revoking.
