Exactly. And not "I don't know, but I believe the tories are all nasty", but "I'd like to see a referendum that has options on the following lines..."
Essentially the non-political reality is that what was promised to voters as being what would happen if we Brexit, and what is actually going to happen are just miles and miles apart. None of the benefits and many of the drawbacks. There's also been the corruption, interference and crime.
People generally are beginning to understand the mess, now. Many desperate for someone to propose something positive, for it to be Labour to do that. But they're not. They're saying the tories are rubbish (true) and then offering / claiming to somehow get something better in the remaining 4 months, via a general election, getting in and then trying to overcome the exact same contradictions as the tories faced regarding the single market and customs Union and free movement etc. Not credible at all. Just more empty slogans.
