Would it Fuck! I recognise you speak for yourself, and i believe you, but you can't actually beleive that would have been the end of it if remain won. The leave camp even promised as much. Not that that is a legitimate reason for a second referendum requirement, just lets not kid ourselves on moral high grounds.
If it was as simple, as was promised, fair enough. It isn't. Even animals re-examie their decisions. Only a perverse abstraction of democracy is what is used to justify marching on blindly into something clearly damaging, which most might not want. A second 'clear' referendum removes that. Then by all means, march away, if that is the transparent choice.
