The good thing about this thread, including the tone of some of the debate, is that it shows the fractures that exist within the UK, which have been exacerbated, though probably not created, by Cameron's decision to hold a referendum.

But conservatives held to their promise to the electorate to hold a referendum,unlike Labour who reneged on their promises.
( 20 April 2004 the PM told Parliament it should debate the European constitutional question "in detail and decide upon it" and "then let the people have the final say".He ended the Commons statement with the war-cry: "Let the issue be put. Let the battle be joined." Fast-forward to the Labour election manifesto in 2005 and the language is as forthright.
Blair promises: "We will put it [the constitution] to the British people in a referendum and campaign wholeheartedly for a Yes vote."

Also worth noting:
the Labour manifesto in 2017 was a hard Brexit manifesto. It promised to leave the European Union by “accepting the result”, and that “freedom of movement will end when we leave the European Union”.
How do our resident lefties square the circle on those little gems?
