I see what you're saying but there are a lot more issues to be considered in a GE as opposed to a referendum vote though and personalities, or lack of, will be a consideration in a GE as well as workers rights, taxation, NHS etc etc. Somebody one may want to lead the country for the next 5 years may not necessarily share the same views on Leaving the EU. As there is likely to be an election either get all the parties to agree that the vote that has happened is it and all agree to leave the EU, unlikely, or get them all to agree that a new referendum would be binding on them all and remove this divisive issue from the normal political arena. Then have a GE otherwise it would appear as though running the country will get mixed up with who shouts loudest about BREXIT and the two aren't necessarily compatible.
The UK appears quite closely balanced between leave and remain and if this is reflected in a GE then there will be no clear majority and you could possibly be back where you all are now. I know if the polls are to be believed then Johnson would win easily. He probably is the best person to have if you want to leave the EU and Corbyn perhaps if you want to remain but are either the best candidate to run the country? This I think will be the crux of the problem for a lot a voters.
OK all pie in the sky and what's it to do with you, you Aussie dingo chaser and I know leave means leave etc. Leave did win but how are you going to move forward with half the country pissed off if you leave and the other half pissed off if you somehow remain?
