To some extent I think I do understand your fears. You think your culture and way of life is under threat - which it is, but not from immigrants. The world is changing fast, and white working class communities in the the UK and USA - and France, for example - are being left behind. Add to that, a world wide recession that replaces well paid jobs in manufacturing with low payed, de-unionised jobs in the service sector, and there's a lot of angry people about. Unless mainstream politicians grasp that, the conditions in which extremism can thrive will continue to be created. But how can mainstream politics address the problem when both Labour and the Tories are part of the problem in the first place?
I agree it's a problem, and one the Labour Party in it's current predicament doesn't look up to solving. On the other hand, there are a lot of thick ****ing racists in Britain, always have been, and now they have a voice. They should be told to shut the **** up. It's not immigrants who ****ed you over, it's unrestrained capitalism of the sort Margaret Thatcher opened the door to. Incidentally, when she did that, lots of people cheered as they bought their council houses and shares in British Gas. Now there's no ****ing council houses and all our public services are ripping us off for profit, let's blame the immigrants shall we? Well you know what, when you start with the racist crap, how about bollocks?
