It's entirely the fault of mainstream muslim and non-muslim community and politicians for not addressing the issue of Islam and multiculturalism in a muscular manner that has led to groups like this. There is a genuine growing discontent with multiculturalism (whatever it means) among the mainstream white population throughout the west. And if their own people won't address the issue, then these grievances get transferred to far right groups and then voila... you have dipshits spweing hate.
No doubt there is some truth in the idea that there is a gap of understanding between Islamists / orthodox Deobandi-type Muslims and the rest of British society, especially in some towns and cities with growing issues of social segregation.
However, after over 20 years of (post Satanic Verses affair) Islamic identity politics, Salafi bullshit extremism, a long line of apprehended jehadi terrorist plots, and actual suicide bombings, the worst that 60 million non Muslims in Britain can produce is a few hundred knuckle-dragging football hooligans peddling the threats of collective punishment in a thuggish street violence mode.
Most people, no matter what issues they have with Islamism, Islamic identity politics, or even Islam itself, don't follow the EDL (and inversely the Islamist) paradigm of collective guilt and ideas of collective communal punishment.
