Nigel: I'm not sure that anything that we could link to would make you optimistic about Brexit.
Dave: That seems very much like you are saying that you cannot find anything. In which case, why did you vote for brexit?
Nigel: I am optimistic about our future.
Dave: I know you are so please share what makes you optimistic so we can all feel more confident.
The two statements you have made seem to be at odds with each other.
Nothing contradictory there at all. I stated that I don’t think I could link to that would make you optimistic.
I am optimistic because I believe that UK can do better when not hampered by membership of EU. However, I don’t think there is much chance of me converting you to optimism about Brexit, as you obviously heard all the arguments (from both sides) prior to the referendum.
The Brexit team did not need (nor could have) persuaded everyone that Brexit would be good for UK. It was sufficient to persuade enough to win the referendum.
