That's a welcome change of tone.
Just as you mentioned about remainers and the EU, I assure you not every single leave voter "hates" the EU, they are concerned about it's current direction. I'd stay in the EU no problems whatsoever, if only it would cease with this incessant drive for more sovereign powers over it's members. Peace, economy and civil liberties come first, and if Johnson cannot deliver, then I hope a no deal will be avoided, and if that means staying in, then we stay in, BUT it must be OUR decision, the electorates, not Parliaments. I used to care about the EU ignoring it's members and forcing them to comply with the decisions made by a minor few who had assumed positions of power, but not anymore. They'll all do what they always do, and I include our own MP's in that regard.
Just as with your feeling of how you're not arsed about being in the EU on any emotional attachment, I really am not arsed about the UK being a "major player" in the world. I'd rather us be more like a Denmark or a Norway or Australia; just doing it's thing, making the people happy, content with their lives, not trying to police the world or set the course of direction we think others should follow.
Climate change is an important issue as is the energy one, and it's those which needs to be sorted in the UN where every nation (is meant to) have an equal voice. I don't want "the strength of the EU" backing us up, getting us involved in their disputes they want to have; we had that as a poodle of the Bush and Reagan Administrations. The whole "EU" thing, just makes me think of things like the Triple Entente, except now the EU's trying to puff out it's chest to Russia and China whilst snubbing the US. Not only is it embarrassing, it's slightly worrying to me.
