I'd want to leave on EFTA terms (preferably) but would accept the WA, reach a Canada style agreement with the EU that kept trade open, and continue to campaign for staying out of the politically motivated EU, but if the vote was to rejoin, i'd accept it. I'd hate it, but i'd accept it and wait around for another campaign to suggest us leaving the EU.
Flexibility of membership of the EU is (meant) to be it's byword and it's most dominant example of democracy. No-one is forced to remain a member for life. Trust me, if THAT stipulation was ever agreed upon by the EU you can be damn well assured i'd be campaigning to sever ALL ties, political and economic, with the EU.
It's only in your opinion that it's a gun being placed to ours heads and a "trigger" being pulled. For many of us we see opportunities to connect with the wider world, outside an isolated bloc that deals with the rest of the world from it's stance and is unforgiving in it's demands. Everyone must agree to EU demands in order to trade with the EU, there's very little give-and-take in my eyes. It is absolutely undemocratic to ask the electorate for it's opinion, disregard the answer as being "are you surrre...?" The main argument from remainers has been "the public has changed it's mind" and therefore it must be honoured and a referendum held. Well we already DID change our minds, in 2016, about membership and we haven't left.
Leave and then campaign to rejoin; no issues from me. Remain via referendum without having left first; absolutely unacceptible. If you're all so certain "remain" would win, why wouldn't "rejoin"?
