"I believe the vast majority of the remain voters HAVE accepted the democratic result now it is the few remoaners who have not."
I don't know how easy it is to know this, but I'm not sure the general election is necessarily the best clue. It's been suggested that, since the Labour party did so well on an essentially pro-Brexit scenario, then there's no support for the Lib Dem position, but the problem is that the Lib Dems didn't really stand much chance of winning anyway, so a lot of people might have worried about wasting a vote on them -- and you sort of need everyone to either know what everyone else is doing, or spontaneously switch to Lib Dem, for a party with 7 MPs to be catapulted to a majority. It just couldn't feasibly happen; voters can't by definition know what the result is going to be, and therefore can't plan their vote accordingly.
That's not to say that I believe that "the Lib Dems would have won the election, if only voters weren't such cowards", but I know for a fact that I voted Labour rather than Lib Dem not because I supported Labour over Lib Dem but because I thought it was the best chance I had to send a message to May along the lines of: "If you must do this damn silly thing, don't do it in this damn silly way." -- and I'm confident that a decent amount of Labour's vote surge came from similarly disgruntled "Remoaners", if you will. There was simply nowhere else to turn if they wanted their voice to be heard -- I mean probably heard, not just lost as noise in various second or third-place finishes that count for nothing.
That's at least one alternative explanation, anyway: Theresa May went to the country to try and sell her plans for Brexit, and the country, as a whole, said "No thanks" by voting for the other lot. It nearly worked, but luckily for her the parliamentary arithmetic's likely to allow her to push through most of her Brexit agenda regardless of the slap in the face she got in June.
Alternatively, perhaps we high-minded politically-engaged individuals at AB are busy pretending that everyone cares deeply about Europe and Brexit and all that, while the truth might be that many people aren't that fussed after all.
