Does anyone remember the 'stiff upper lip' of the British? The fighting spirit? The indomitable people who once ran a big chunk of the planet, and who could chase away armed guerillas with a walking stick and an angry voice? A people who, nevertheless, could laugh at themselves and had a great, if sometimes cruel, sense of humour? What happened to them?
Those people would never have set off a security scare because a schoolboy dressed up as the Joker and waved a plastic gun around. Those people would never have arrested a man in fancy dress because he had a plastic knife as part of his outfit (tipped by anon in the comments here). Those people would not have shrieked 'Terrorist!' at the sight of a plastic halloween skeleton. The first might have earned a caning, but not expulsion. The second and third should not even have raised an eyebrow. Neither should Old Holborn's walk.
The people who replaced those real British are spineless weaklings who jump at shadows. Who call the police if they are slightly offended by a word or two. Worse, the police respond not by saying 'It's nothing, don't worry about it', but by harassing and usually arresting anyone complained about, no matter how trivial and all too often, no matter whether an offence has been committed or not.
I implore you to go and read the whole thing. If there is a more salient evaluation of the state of the nation, I have yet to see it.
