I don't think he is saying it wasn't or comparing the two, as I read that.
Think the suggestion is a 2 stage vote. One on wanting it, two on definitely
wanting it, in its final format, or abandoning it.
Which, in hindsight, would have been good with Brexit. Not sure if it would have made much difference at the time, doubt anyone was less determined through the 2.5 years of shite between the vote and the final exit.
Maybe we should have a 3rd vote, once we've seen the reality 2 years later and realized how fucking wrong we were, an extra life restart the game!
Joking aside with the last bit, I actually think the original suggestion itself is a fine one and would not have have an issue with it. Unlikely to happen though. But would be a more sensible way to tackle it for sure.
