Brexit would go a lot smoother were it not for the remainers continually complaining about one thing that is now history........that being that the Referendum has been fought and won and is over.
If you honestly believed (you don't) that pointing out problems is what causes them, then you and the other Quitters should join hands and dance round singing "everything's fine" until everything becomes fine.
Though you must also take the blame for forty years of constant carping by the anti-foreigner moaners and their silly made-up complaints about straight bananas and London busses.
