May is probably a lovely person. But missing a crucial part of her brain. She is the problem, and the civil servants whom she let run this shambles.
And the people have already decided. If there’s another referendum (depending on the choices) it could make things worse: Civil disobedience, riots, boycotting of the referendum. (Although I’d have a side bet on apathy, and nothing happening!)
It was made clear before the vote that it would be implemented. It was in the major parties’ manifestos. So it would be hard to justify, unless Stay wasn’t in the options.
If Stay is included then everyone is really saying that a second referendum is just an excuse to stay. That’s all the Remoaners’ assumption. But it’s not clear the result would be different. There’s now soooo much evidence that the EU is evil, that the sky hasn’t fallen down, that the most lies have been told by remainers, that remainers have been the ones who’ve buggered this up. The analogy for the final point is that if half your football team is deliberately scoring own goals it doesn’t mean your team couldn’t be great, you just need to chuck the saboteurs.
