It looked like the flagellates during the black plague at the beginning carrying the crosses.
It is free speech. And Muslims are not free to threaten people who deride their god. It's Britain not Bahrain. The same in Paris with Charlie Hebdo. Freedom of speech and you don't get to threaten or kill people because your religion is easily offended. Same in the US.
I do think if Muslims in any of these European countries attempt to start voting in and implementing religious law will see violent resistance.
Some of them do seem to believe their religion is taking over the world, and any inclination towards this whether it is by religion or Nazi dogma or any other mental disorder, it will be and rightfully should be opposed, with force if neccessary.
You worship in peace and follow the laws of the land you move to, no problem. You start forcing everyone else to live your religion and you will soon find the Western democracies DO talk softly but carry a big stick.
