I was aware of what you meant - and I still disagree. The terms ought to have been thrashed out and/or more provisos and choices inserted in the referendum before it was put to the poll. Instead, the MP's settled on a straight in or out choice.
The electorate knew it was a simple choice, and they voted accordingly. In or out. Nothing else matters now.
You can't order a plain cheese pizza then complain there's no other toppings or it's the wrong type of cheese. Nor can you send it back after taking a vote on what cheese/toppings you want. The pizza was ordered with the consent and consensus that the electorate was happy with the choices at the start.
And even if there were to be any vote then the electorate should be asked again - not the self-serving politicians who now whine because they didn't get their preferred result because they were far too complacent of the plebs.
Think this was more down to Cameron thinking the remain vote would piss it.
