I'm probably stating the obvious here but the referendum was about whether we remained in the EU or not and we know what the outcome was.
And every time we have a general election, whoever ends up on the losing side still campaigns against the government, and policies end up being discussed, argued for and against and no-one calls the opposition "whingers" or "moaners".
Why should the losers of a single issue (albeit a big issue) referendum be any different?
There will be 45 years worth of legislation to trawl through to repeal and replace with UK versions and a lot of the "fine detail" will actually be very important to lots of voters, both "Leave" and "Remain". For instance, will access to European health services be available if you fall ill on holiday. Closer to home, perhaps, will the FA be able to establish quotas on foreign players in professional football.
There's lots to so and a lot of debating and negotiating to do over the next 12 months and to suggest that people can argue against the Government of the day on things like the NI changes for self-employed people, but not against, say, access to fishing grounds, seems ridiculous.
