oh well.. you know the old saying... if you don't engage in the process you can't complain at the outcome....
OK, I'll bite. Personally, leaving the EU, even without any agreed deal, it won't affect me enough to bother me. I'm retired, own my house, have a reasonable pension, enough savings, OK health for my age, live in an area where immigrants are treated like human beings, and am not a slave to a motor car. So if I was to engage in the execution of the 2016 referendum result, what would I do? Well I'd start from the optimum position using the letter of the referendum question:
1) the result (by less than 2.73% of registered voters) was in favour of leaving the EU
2) I would support delivering what the electorate voted for i.e probably the best chance of success would be for a so called 'Norway' arrangement. Maybe a bit naïve thinking that the leavers would also respect the result of the referendum, it would probably be fairly easy to get full agreement on from the EU and we would by now be well into the leaving process planning.
3) Being slightly more realistic, the leavers, whilst saying that they would accept such an arrangement before the result was known, are now demanding more than voters were asked for. So bringing us up to the present situation (which could have been arrived at about a year ago) I would insist that the electorate were asked to choose from the available choices rather than doggedly pursue a result from 29 months ago when a large proportion of the voters demonstrably didn't have enough information on which to make a decision that would set the direction of the UK for the forseeable future.
OK, so that is a true supporter of the EU fully engaging in the result, the process for delivering the result and what to do when the negotiators have lost their way, (as is the situation now). My personal preference would be to keep the status quo, but as you want to see what a remain voter's engagement might be like, there it is.
