I understand the confusion. There are a lot of people who voted to remain in the EU (48%). I have no idea why they associate the EU with tolerance and kindness.
But the key is that they lost the vote. The majority wanted to leave (52%). This is how democracy works. Even if the margin is small (4%), the winner wins and the loser is out of luck.
It wasn't a conservative versus liberal argument. There were folks from either side of the normal divide for and against leaving. London, Scotland and Northern Ireland were most in favour of remaining. Most of everywhere else wanted to leave.
No one I know voted for Brexit because they were against tolerance and kindness. They mostly voted for Brexit because they wanted Britain to remain independent and because the EU is an imperial organism. Some voted to keep foreigners out. There are always some of those people everywhere, but polls have suggested the key issue for Brexiters was sovereignty.
So that's the science of my interpretation of the result. It also happens to be the key for me. The history of the Germans and the French is known to everyone. They always plan for a new "Roman" empire. They cannot help themselves.
The remainers may well be right that in the short run, leaving the EU will cause some economic disruption. So I am willing to take that punch on the nose.
I also think that there are opportunities around the world, and the EU promotes tariffs in trading with non-EU countries. Many of those are our best friends in the world. So it's worth looking around for new growth opportunities in emerging markets as well. The EU, taken as a whole, is a low growth space. Why hitch yourself to that wagon? In the long run, operating in a world marketplace on a level playing field is more interesting than trading preferentially with EU countries.
People who write music are not usually the sort of folks I turn to for understanding politics! It's hard enough without trying to set it to music. Also, an unelected person on the losing side of a massive referendum shouldn't claim to apologise for his own country. He can express regret, but he represents only his own opinion. If you honour democracy, and this was an exercise in pure democracy, not of parties or parliament, you accept its results.
By the way, I have no idea who that guy is. It would be nice if US media would spend more time talking to the numerous sensible people who voted for Brexit.
