Well, then leave.
You know, I'm 50 and I've been following this since the days of Mrs. T and her handbagging of the other EC leaders and her "I want my money back". Ever since, every British PM has been acting as a petulant child in the EC/EU and complaining that they're still paying too much into it, and that they don't want to participate in Schengen because it brings rabies, and don't want to participate with the Euro because the vaunted Sterling is still world currency, and don't want to participate in the Social Charter because British employers must be able to exploit their workers like in the days of Marx and Engels. And so on and so on. And ever since, there's been this constant droning voice in British politics, in both major parties, that they want out again.
You know, I'm totally sick of it, and to Mrs. T, and Boris and Farage and you I say: good riddance, don't let the door hit you in the face on the way out. And at the same time, I feel sorry for the many rational thinking Brits who understand that their future lies with further cooperation with the continent, and with people like The Don who now must fear going out of business because of this utterly foolish decision.
