You couldn't force the EU into anything. That's what you've never understood - the UK wasn't in a position of power over this at any stage. We simultaneously have more to lose economically and less to lose existentially, meaning the EU can't afford to give us anything.
But as I've said you've never understood that, so your default position now is to blame Remainers for trying to get something together that isn't a total beating by the EU that would destroy our economy. That's what the Chequers Deal is - a last-gasp attempt to get something at least plausible together, and even then the EU won't accept it and the Tory right won't, so it's pointless - but it was the only thing she could try to do. The alternative is being a lunatic and leaving negotiations/no deal.
Tell me this Joey - how was Brexit ever workable? We were told it was going to be 'easy', free trade deals all over the shop, the EU would bend over to accommodate us, we'll thrive, the NHS will get more money, Britain will be a world power again... can't you at least accept now that it was all, literally all of it, a tissue of lies and the vote was sold on those lies rather than anything of substance whatsoever?
