I have just watched the programme.
Nothing really changes - we have a group of largely uneducated men who have too much free time and too much of an over-developed sense of self-righteousness.
The links are the same as football hooligans - the need to feel loved and supported by people who think the same. They enjoy their 'siege' mentality, the idea that only they can protect their homes from rampaging invaders, it makes them feel important and that they belong to something which satisfies their deep seated fear that they are not making any sort of impact on the world around them.
Their anger and ugly attitudes also reek of fear, and their willingness to confront any and everyone, be it police, citizens, even each other, shows how deeply unhappy they all are.
Fortunately they are, and always will be a small, if vocal minority who hold no sustainable views, or support.
Best ignored, like noisy children, they will get bored and go away.
