The EDL thrive on fear, usually unfounded or illogical fear. I know plenty of people down here in Kent who left London because of the fear of black people taking over their neighbourhoods. There's a sizeable black community now who have moved down from London also.
It's understandable to be concerned when things change and some people fear the erosion of their way of life - there's nothing stronger than the pull of home is there? If home is recognisably different with languages and cultural influences that people feel excluded from then fear follows. That's what the EDL prey on. They take the most extreme elements of Muslim faith, suggest that they exist and thrive in our midst, tell people that no-one is challenging it and offer a visible and vocal opposition to a problem that is largely absent from our shores.
So yes, you could argue that there is a resonance in some of what they say. I suggest it's fuelled by nationalism and bigotry though. I see them as national socialists and anyone who supports them for whatever reason also supports that doctrine.
It would appear that their founder also thinks that, but we'll see how this pans out. Maybe he's just shit scared of getting his head kicked in.
