Re: One viable option
The referendum was won against a government sponsored remain campaign (including a much flaunted 'special deal' Cameron 'won' from the EU, and a huge publicity drive through the BBC and a leaflet).
The referendum is advisory - after all parliament is supposedly 'soveriegn' BUT the parliament consists of people whose job it is to represent the very constituents that voted to leave - thus not leaving (as I think May actually intends) is against the democratic vote and the job the MPs are there to do.
The facts are also clear - since we joined our debt has increased, our taxes have increased, our trade deficit has increased, our unemployment has increased, our manufacturing has shrunk, our services have shrunk, we have had to rasied money through selling all our public utilities and companies to foreign (often foreign government) ownership, we have decimated (and worse) our military to the point they can't defend the Isle of White never mind the UK.... if you really think any of this is good you are quite off your trolley.
Worse of all is that we have bred several generations of people totally and utterly unable to believe in themselves, their abilities or even the abilities of their countrymen who now feel that the UK can't manage without the supposed cooperation of a bunch who have never been allies (even the French in the last war against Germany refused to give us their navy so we had to sink it to stop them giving it to their new friends). None of these supposed allies actually abide by the rules that are imposed on us (the Germans back their automotive industry to the tunes of billions a year via direct purchase of ALL government vehicles from Germany regardless of cost, quality or any other criteria) while the French stand by and watch their farmers destroy any imports...
