Re: What I don't understand
Is this the standard by which you would have all our votes decided? Nothing would ever pass, especially given that it would give scaremongering so much more weight. People seek comfort in the status quo, even if it is to their detriment, it's very easy to tempt people into the stability of keeping people in the safety of what they already know rather than the scary uncertainty of what they don't.
If it's accepted as fact that leave made 'promises' that weren't factual (they aren't the gov so they couldn't make promises - they aren't the ones who could actually enact them), then it should be also accepted as fact that remain did engage in Project Fear. It was pretty much constant doomsaying and preying on the innate fears that come with uncertainty. People were told there would be no medicine, prices would go out of control, we'd not be able to travel, food would be scarce and that we'd become a 3rd world country overnight.
Also, if the vote came out the other way, 52% remain, should we keep going until there is a supermajority for remain? What would we do in the meanwhile? After all, it could go to votes ad infinitum, but the turnout would never go higher. Would we be half-in/half-out whilst it's decided?
One and done, simple majority is the only way to answer the yes/no question. 2/3 is just an arbitrary standard, plucked out of thin air. You may as well ask for a 4/7ths majority or a 5/9ths majority for as much sense as 2/3rds makes.
