"I similarly don’t really understand your ‘Remainer/Brexiteer’ reference."

I think you do, just don't like the answer!

When we were in EU we were "one economic entity" and nationality didn't matter - in employment, residence, trade, tarrifs etc and so to mobility of capital across member state borders. So eg French ownership of a British key industry was a very "EU thing" and part of what economically bound us together.

Yet you've gone very "little Englander" on this matter which is very inconsistent with your remain stance. Nothing the matter with that, but it's no different to Tricky not wanting to be served by a Slovakian barista in a coffee shop is it? 😊
