You stated you were more wedded to democracy than wedded to Brexit, so I asked which form of democracy are you wedded to? I think that's reasonable.
Your response implies to me you are more wedded to Brexit than than you state.
How the referendum should have been run and the question asked should be of great concern to you as a believer in democracy. As it stands Parliament can still respect the result by negotiating a deal and putting that to the people. The majority voted to leave, here is what leave actually looks like, do you still want to go ahead? That is democracy in action.
I don't think your examples of a byelection and GE work here, someone more learned than me on the topic may well set me straight.
A more apt, if extreme example would be if the referendum was on the Death Penalty with a yes or no answer. Yes wins but parliament can't decide on what the death penalty should be implemented for. An extremist section of the Government in charge gains influence and pushes for death for all crimes committed (this scenario's version of a no deal).
If you had voted yes on the presumption of it being only introduced for 1st degree murder as that what was campaigned for, would you still respect the result and state you knew what you were voting for?
Stating people have won and lost (especially when you don't know what it is that has been won) adds nothing and shuts down the debate.
Actually that's a good question, what is it that has been won? What does winning look like to you? Do you think what winning looks like to you is achievable? and finally do you believe that all those who voted leave shame the same opinion as you as to what winning looks like?
For a bit of fun; you state that everyone knew the rules of the referendum, so they knew it wasn't legally binding (yes MPs said they'd respect the result) and can't complain if parliament decides to just put Brexit in the bin ;-)
