You are making a normative claim (what you want). Not a nominal one (what is). Completely irrelevant, the UK cannot be outside of Europe geographically because of your feelings.
Not with that kind of attitude! We have machines that can consume the Hambach Forest, and explosives powerful enough to crack landmasses. Sure, we might have to temporarily evacuate the populace near the border, so that they survive, but I'm sure we can evict England from Europe if we really put our minds to it.
