typically we practice more complex implementations of democracy and as a rule we use majority rule for things like social questions as opposed to key strategic and economic ones.
Or do you subscribe to the point of view that we should only have had a single general election and abide by that result for all time?
If we weren't asked whether we wanted to join a post-Lisbon Treaty EU, and once we were in it, we actively said we don't want it, why should we remain in it?
General election results must also be respected, but they revolve around a number of issues, so are not a good indicator of voters' opinion of membership of the EU.
Besides, the Conservatives were elected into government with a manifesto promising an in-out referendum. The government has delivered on that promise and is carrying out the will of the people, as decided in that referendum.
It is being respected. This might be news to you, but we don't live in a fascist dictatorship where dissent is forbidden.
So, in your view, not a single thing any government has done (with the exception of joining the Common Market) has been agreed to by the population. Interesting.
We did agree to be in the EU.
In any case, I trust you'll never vote again or protest against any voting outcomes that you disagree with as you seem to think that once a vote has been held, the outcome can never be disagreed with.
I don't expect everyone to be happy about the outcome of votes, but I do expect outcomes to be respected.
I'm not opposed to decisions being overturned, but I don't think it's right to re-run a vote right after it has been carried out. We haven't even left the EU yet. At some point after we've left the EU, perhaps there will be grounds to take another look at membership of the EU. But not straight away.
I want as many people as possible to participate in elections and referendums (even if I disagree with them), because I want everyone's voice to be heard. That's what it means to live in a democracy. And so I certainly intend to continue voting.
The number of people who claimed to wish they could change their vote after the result was surprising. How many referendums do we need before people decide they've voted "properly"?
Maybe that's the reasons why direct democracy by means of referendums is [considered to be] not always a good idea.
You seem to be trying a reductio ad absurdum argument here and failing.
The UK joined the EEC in 1973, without a referendum but based on an act of Parliament. In 1975 they held an explicitly non-binding referendum that supported staying in the EEC. In other words, that referendum voted to maintain the status quo. You can "disregard" it if you wish, but that would also just mean maintaining the status quo.
The UK has never held a binding referendum on EEC/EU membership. According to the UK's crufty "constitution", this means Parliament gets to decide. If Parliament does nothing, the UK remains in the EU.
