One thing Brexit has done for sure is to show us who the arrogant, patronising, pedantic, non patriotic people are in this country, I think Remainers have to agree with that.
Two things really. Geographically we're an island nation (or group of nations) separate from the main European continent, but more importantly from my point of view, I think anything that threatens to 'lock' us into the European political superstructure needs to be opposed, and that's always what the European Union will be about, sometimes very obviously and sometimes more subtly disguised.
Brexit was a step in the right direction in terms of making that more difficult to do, and giving the British public the opportunity to express their view, but of course it was never going to mean the European 'blob' was going to give up trying to exert its influence. We've seen it since through various manipulative efforts to try to discredit and reverse the outcome and gaslight those who voted leave into thinking it was a mistake.
Being arrogant, patronising and pedantic has nothing to do with wanting the best for your country. The irony of your first sentence though EP.
