Love the templar imagery. They claim they only hate fundamentalist Islam yet they call themselves crusaders.
Also, weren't the Templars a largley French organisation? Or at least founded by a French man? The sort of people who join the EDL are not known for their love for the French.
Edit: Also worthy of note I feel is that their beloved St George, whose cross is so proudly displayed on that banner as it's the English flag, was from the middle east. He may have been Christian but that still has a certain amount of irony for a racist group who focus their racism on poeople from the middle east.
