You're right about the many people L R, but unfortunately for you not nearly enough.
I dunno, according to an average of 11 polls Oct to Dec, 39% think leaving was right versus 49% who think it was wrong. When asked how people would vote on the same question (leave or remain) today 47% would vote leave versus 53% remain (
source).
Now of course remain is not an option and when you switch it to applying to rejoin we get a narrow majority for staying out: 51% versus 49%. However, this is before any of the real consequences have actually happened. I think there's very little doubt that once they do, many more people are likely to back rejoining.
The younger generations were always much more pro EU than the old fools who voted to leave, so a majority in favour of rejoining is probably only a few months to a year or so away. It may take longer for a serious political movement to take up the cause but I'm much more confident that we'll see the UK rejoin within, perhaps, the next decade.
We wont get all the same concessions, opt-outs, and discount we had before - the old fools have thrown those away for less than nothing - a few years of economic hardship, lost jobs, and lost livelihoods. Such a pointless waste.
