There was a single referendum, and it was won by those who voted for 'Brexit'. Let's just get on with it.

I have no problem with the first sentence. However, the second relies on an understanding of what the 'it' we are getting on with is. For example, I have no idea if you believe(d) your 'Leave' vote was also a vote to leave the Galileo project, even if it may cost us billions to build our own. If you think it did - which I don't know - neither of us has any idea if that is what other people who voted leave intended. And we could make the same point for (probably) hundreds of other points of detail.
