The thing with the edl and all the other 'hate groups' that spring up the moment it looks like any other marginalised group is getting or likely to get equal 'rights' is that there is an overwhelming sense of entitlement and jealousy.
I personally do feel that certain aspects of 'english' culture have changed but this has more to do with a culture evolving due to changing attitudes rather then because of 'immigrants'.
Jobs for life no longer exist but this has much more to do with changing business practices, women in the workplace and technological advances as it does having a growing immigrant workforce.
Expectations have also changed as consumerism has become the new religion and internet shopping the new 'church'.
Communities have mutated where once whole towns were built around a factory or a mine and people would live in one place their entire lives, the pursuit of home ownership and the ability to travel greater distances has ment that in order to feel part of a community more effort is involved.
It is this need to identify as being part of a 'group' that leads individuals to join organisations such as the edl or a conspiracy group or shed lovers uk or whatever group it is that offers a similar world view and motivation as your own.
Marginalised peoples often form very close knit, proactive group in order to protect their interests whether it be feminists, homosexuals, immigrants or scientologists.
The white 'english' heterosexual male has had his world changed dramatically since the world wars. No longer the 'king of his castle', numero uno, judge jury and executioner.
For many males this is not an issue far from being threatened by the equality being granted others he embraces it adapts and welcomes the changes and the challenges living in a more equal society brings. For others the loss of 'status' is too much and they hark back with rose tinted glasses to the halcyon days where they were at the top of their foodchain that reinforces their superiority complex.
Womens roles in such groups as the edl are a little more complex I think in part a backlash against perceived female subjugation - part pure bigotry and part 'stand by your man'
