Its time for people to grow up and accept whats happened.
We have. I totally accept what has happened. The question is - what are we going to do about it?
An analogy:-
The owners of an office block run a staff referendum to decide whether the office block should have a swimming pool on the 10th floor or a 20 storey building. They aren't able to demonstrate any real benefits to having a swimming pool, whilst the staff who disagree are concerned that it will be pointless, costly and reduce the amount of business the company is able to do.
They lose the vote. The swimming pool is built - hurrah! We are now at the point where were we have realised that no-one can get past the 10th floor as the lifts were removed to make the pool the right size. The lining is leaking and water is slowly destroying the lower offices, and the heating system has failed. To add to that an architectural survey has revealed that if we don't do something the building will collapse. In the meantime, the business has lost huge amounts of money and productivity, very few people are happy except for those few still swimming in the freezing cold pool shouting "we have a pool isn't it great!".
We have Brexit. It has happened. We can clearly see the impact and how it is destroying the country. We now need change. We need to re-join the single market and negotiate for a Norway type relationship with the EU so that we can restore trade and rescue the economy.
