Ah right. Gordon Brown press ganged Cameron into calling a referendum 6 years in the future
You can't seem to grasp that background to Brexit isn't some new phenomena created 3 years ago.
Historical apathy to Europe goes back much further on a cross party voter basis. 1975 referendum Labour was split on remaining in EEC. Labour conference in 1975 overwhelmingly voted to leave. 1983 election they campaigned on taking Britain out of Europe. In fact until Blair & new Labour came along Labour was basically an anti EEC party.
You can decry the calling of a referendum and ignore a general UK apathy towards the EU that has lasted basically up until the referendum was called. Where were all these passionate views on Europe in the 2014 European elections when only about 35% bothered to vote. Maybe this new found passion on the issue would have been better directed through the ballot box. Too many people have found the Euro religion far too late to make a difference.
Perhaps if Brown had kept Labour promise over a referendum we wouldn't be in this current situation.
Cameron and other politicians will be judged and found wanting as to how badly they read the British electorate - maybe they expected the usual antipathy of the British public and not the highly charged issue it turned into.
Brexit has always had a touch of inevitability about it just the Captain hindsight of today choose to ignore it and concentrate on blaming others rather than admitting they should have worked harder and longer about preventing a situation all parties have been responsible in creating.
