That's what comes of trying to convert fantasy into reality.
It's not that leaving the EU is impossible, just that leaving and keeping to all the needless, self imposed UK government red lines (some of which contradict each other ) and adhering to EU rules that can't be altered without EU treaty (despite leading brexteemists stating otherwise) changes and without trashing the economy is far more difficult than any of the brexteemists falsely assured the public it would be.
But I'm not just being a whiney "remoner"; I do actually think that brexit could have been achieved successfully with minimal disruption, but not the way that would have been acceptable to the politicians and, possibly more importantly, the press. On the previous thread I outlined the way I'd have gone about it. I'm not going to go through it all again, but it's there if you want to take a look. So don't moan at the likes of me who has been saying that the process of leaving would be tough, time consuming and intricate, direct your anger, if angry you are, to the likes of those above who have lied and lied again about the whole brexit debacle and their part in it.
