One of the main Brexit promises was "“we send the EU £350 million a week – let's fund our NHS instead” - was a lie, was never going to happen and the NHS has got worse
People pointed out at the time that the UK literally never gave 350 million a week to the EU in the first place, and that a significant fraction of the much smaller amount of money that it did give to the EU was spend on projects in the UK anyway.
Given the discussions at the time, I think this changed nobody's mind.
Yeah, I remember some of those threads here, back when the “libertarians” and right-wing UK posters weren’t quietly distancing themselves from it. It was very obvious that even people who sounded rational were confabulating excuses for what they were going to do anyway from the way they’d just smoothly pivot to something else whenever pushed for support on that figure.
