Re: Could a brexiter please explain...
You are making the mistake of attributing rational thought processes to brexiteers. Remember, these are the people who won a referendum to leave the EU with no plan at all about how that would work and no understanding that things like Northern Ireland might present a littly problem (generally, brexiters don't really have a very strong idea that anywhere other than England really exists). Now, after having fucked the country for three-and-a-half years, now we're about to leave, they have no plan at all for what will happen after the end of the year.
But of course, always remember: it's the fault of the remainers. It's the remainers who should have made the plans for leaving. Of course it is, how obvious!
