The overwhelming majority of the British public see these kinds of things as grossly offensive and in cases have created petitions wanting stuff like this to be illegal.
This first blew up when the group "Islam4UK" demonstrated in Luton against the royal anglian regiment's homecoming parade. This spawned the EDL group to counter-protest.
They later threatened to demonstrate in Wootton Basset (where dead soldiers are repatriated) and the uproar against this was huge with major newspapers all calling for the march to be banned.
It is now illegal to be a member of the Islam4UK group, so they have had to change their name a bunch of times.
