As that's not on offer, abstention in the referendum seems the best option.
As ever, there is not a box on the ballot paper marked "I abstain" or "None of the above" to enable an expression of positive engagement to be made by electors, rather than just being taken as apathy and a failure to bother to vote.
Turnout is predicted to be around 25%. I don't think that kind of a turnout gives the result any validity.
